  • Live quiz is now on the homepage and in the portal's Games section. Enter the game PIN from the classroom screen to join.
  • S.2 Integrated Science students now have a QBank: 39 practice questions on Unit 7 Living Things and Air, sorted by textbook section. S.2 questions appear only for S.2 courses.
  • Sign-up and profile editing now support every form from S1 to S6.
  • New S.3 course selector: tick the Physics, Chemistry and Biology topics your school teaches, choose first or second semester for each, and get a short plan showing which regular units cover them, which enrichment courses come earlier, and where to enrol.
  • Nearly every Physics question in the practice question bank can now be read in Traditional Chinese: 1,339 of 1,362, up from 520. This adds 819 Heat, Optics and other Physics questions, with Chinese wording for the questions, options and answers. Most worked solutions are still in English.
  • The Science challenge now builds from familiar facts to demanding reasoning. Five score titles run from Science Spark to Science Legend: 13–14 correct earns Science Genius, and 15 earns Science Legend. This version has its own statistics; earlier scores remain.
  • The Science challenge now focuses on everyday science and reasoning, with 15 bilingual questions and short explanations. The new question set has its own statistics; earlier scores are preserved.
  • From Regular 3 (11 Nov 2026): the Friday S.4 regular class in Mong Kok moves to 17:00–18:30, and the Friday S.3 add-on moves to 18:25–19:40 (they swap order). See Courses.
  • S.2 Science Word Game is now called Science Adventure. It still covers the S.2 Science key terms, and older students are welcome to play it too.
  • Biology Word Game and S.2 Science Word Game now play as one campaign. Levels go section by section, and the last level is a final challenge on the whole syllabus (Easy, Hard or Hell) that wins a bronze, silver or gold trophy. You can skip straight to it. Clearing it unlocks Infinite practice. Timed mode is gone, and Survival scores carry over to the final challenge leaderboard. Letter boxes now show each missing letter clearly.
  • The Features page is up to date: the practice question bank, Daily challenge, homework results, word games and the Science challenge now sit beside the classroom quiz, Ranked duels and bilingual notes, each with one simple picture.
  • The updated 50-page S3 Subject Choice Seminar slides are available on the seminar page, including course features and demonstrations of the online learning tools.
  • The free Science challenge has 15 bilingual Physics, Chemistry and Biology questions, instant answers and a downloadable story card. No account is needed; anonymous play statistics appear after 200 submitted plays.
  • New game: the S.2 Science Word Game, for revising the key terms of the S.2 Science textbooks (Units 7 to 11, 181 keywords). Fill the missing keyword in a sentence. Campaign mode takes you section by section: clear each level with hearts left to collect an item for your lab shelf, gold if you lose no heart. Infinite, Timed and Survival modes have their own leaderboards. It is on the home page under Games.
  • QBank has visible English and Traditional Chinese controls, Chinese Physics topic labels, and keeps the selected question and open answer when you change language.題庫提供清晰的英文及繁體中文切換按鈕和中文物理課題標籤；切換語言時會保留目前題目及已開啟的答案。
  • Reg 1 written quizzes now provide English and Chinese answer-key downloads after you submit. Marks and feedback appear when your teacher releases them. Each quiz opens automatically at its scheduled lesson time.
  • Biology Word Game has a Campaign mode: study chapter by chapter, and clear each chapter's level with hearts left to collect an organ for your body map. Clear it without losing a heart for a gold organ. Progress saves to your account.
  • Biology Word Game adds three DSE chapters: Gas exchange in humans (Book 1B), Reproduction in humans and Detecting the environment (Book 2). The pool is now 650 keywords.
  • Biology Word Game is rebuilt to match the Chemistry Quiz: Infinite, Timed and Survival modes, now with 457 keywords taken from every chapter glossary (one- and two-word terms such as active site and vena cava). Hints can reveal a letter or the Chinese meaning; a correct answer always keeps at least 2 points. In Survival a hint costs a heart, and Hell gives no hints. Practise any mix of books or chapters; only whole-syllabus runs go on the leaderboard. It is also on the home page under Games.
  • The Daily Challenge has its own page at /daily: today's question, your streak, a 28-day calendar and the trophy ladder. Public visitors see today's subjects and yesterday's results without the question. S4–S6 students now get their own subject every day (S4 Physics gets Physics), while S3 keeps rotating Physics, Chemistry and Biology.
  • QBank Daily Challenge now shows yesterday's result when enough students answered. After you answer a practice question, you can see how many students got it right.
  • Biology Word Game adds S.3 and DSE chapter practice: fill one missing English keyword, reveal letters for fewer points, and compare published scores.
  • Fill-in-the-blank questions in QBank now let you type answers and check each blank. Hints show the answer pattern before you check.
  • QBank Daily Challenge gives students in the same form one shared science question each day, with streaks and milestone trophies. A 30-day streak makes them eligible to claim a reward from A. Lam.
  • QBank has a "Show timer" option: a stopwatch counts up from 00:00 on each question, next to the DSE pace target (about 1:30 per MC, 1.2 minutes per mark for long questions). It turns amber when you pass the target and red at double, and stops when you answer.
  • QBank practice now shuffles questions by default, so easy and hard ones come mixed. You can still pick "Ascending difficulty" or "Newest paper first" under Order.
  • Summer 2 homework is open again for late submission (補交) until 26 Nov 23:59 for students who had not submitted. Your personal deadline shows on the homework page.
  • Adapted practice questions are labelled “Adapted from public exam” and can be found with the new source filter.
  • S.3 Enrichment module 1 now meets at Prince Edward (Hip Shing Hong) on Tuesdays, 6, 13 and 20 Oct; Courses and Calendar show the new dates.
  • The S.2 online course now has an Enrol button on the Courses page.

  • Completed Summer 2 reviews can now be explicitly released after all official marks are saved, including papers that originally received AI suggestions.
  • Teachers can save individual question parts without filling every score. Drawings-only review remembers completed drawings separately from pending text answers; untouched AI suggestions stay pending.
  • Summer 2: after your teacher releases your result, read the marking scheme and diagrams directly on your paper, even while submissions remain open. The focused teacher marking queue skips automatically marked MC questions.
  • Text marking shows the official bilingual answer for the selected subpart. AI feedback keeps its yellow background, with a button to add it to your editable comment; repeated grading metadata is removed.
  • The homepage keeps account controls and navigation on separate rows so signing in does not cut off menu links.
  • Public-page menus now use consistent labels, and phone users can scroll through every available link. Game menus include Account. Mistyped addresses show a page-not-found screen with links back to the site.
  • Teacher marking groups text answers and editable scores into a compact overview, with feedback and question details available on expansion. Drawings retain their large review view.
  • E-marking has a focused page: press Enter to save official marks and continue with the next student. Returning resumes the same question at the first unfinished student. AI feedback suggests editable error tags.

  • 《全年課程年曆》改用網站統一設計。年曆頁換上同主站一致嘅版面,主頁選單、課程一欄同頁尾都加咗入口,想睇開課日期同課題更容易搵到:alamscience.com/courses#overview。
  • 新增《全年課程年曆》。2026-27 學年 S.2、S.3 綜合科學同 S.4 物理嘅常規課程開課時間、每期課題、增潤課程同 One-Day 試堂,一頁睇晒:alamscience.com/courses#overview。
  • 課堂問答比賽唔會再跳題。之前主持連續撳兩下 Advance，有機會直接跳過最後一題。而家每題公佈答案後要先出排行榜先行得下一題，撳快咗嗰下唔會計數。
  • 公佈答案之後，手機會繼續顯示你嗰題嘅結果，一路睇到排行榜出埋為止。
  • The 2026 subject-selection seminar now has a full reference page. Parents and students can revisit the complete cohort, DSE, JUPAS, subject-result and university-weighting tables, follow the original sources, and download the seminar PowerPoint.
  • ALAM Science now connects its Features and Courses. The learning-system page brings together classroom quiz, Ranked, teacher-marked paper work and the content pipeline; the course overview lists current S.2–3 Science, S.4 Physics and online intensive choices with direct DE detail links.
  • Ranked is now labelled as a public beta. Any free public account can enter placement and Ranked play; the ladder and casual chemistry practice remain open to guests.
  • The One-Day examples are now evergreen. S.2–3 uses the first-20-elements story with the element game, while S.4 demonstrates SUVAT kinematics.
  • The public site now shares one lab-notebook identity. The home page is a clear front door for courses, free practice and student tools; course, member, update, guide and live-quiz pages now use the same responsive navigation and accessible controls.
  • Sharing and archived events are clearer. Public pages now have descriptive browser titles, social previews and an ALAMSCIENCE favicon. Completed July One-Day pages are labelled as archives and direct visitors to current course information.
  • Chemistry answer matching improved: Ranked Duels now accepts correct equivalent names such as gallium(III) hydrogensulphate, while elemental molecules use the familiar DSE names fluorine, chlorine, bromine, and iodine.
  • Ranked now gives you three clear choices. Live Match waits for a real player online now, Ghost Match starts immediately against a recorded player run, and Practice gives you an unranked set with no Elo or season-record changes. An empty live queue never switches modes for you.
  • Ranked results now teach after every duel. The full result screen appears immediately with your submitted answer, the correct answer, a chemistry summary, both players' accuracy and timing, and your Elo movement.
  • Osmium and Iridium house opponents are now human-beatable. They remain strong and bounded, but no longer demand a flawless machine-speed run every game.
  • Ranked now matches players live. After placement, two compatible players searching together enter the same room, race the same questions simultaneously, and see each other's progress in real time. If nobody joins within eight seconds, the search stops and lets you choose whether to try again or play a ghost.
  • Recorded players stay in the fight too. The fallback prefers unseen player ghosts, can use a nearby-tier human run when the exact tier is empty, and allows a rematch on a later day before using a house bot.
  • Ranked placement now learns your level. New players begin with an all-easy set and a gentle house opponent; 8–10 correct raises the next set one step, 6–7 holds, and 0–5 lowers it. All 10 placement duels use calibrated bots, and your final metal rank follows the level you actually demonstrated.
  • The private Player Activity ledger now shows Ranked duels alongside classic quiz submissions, including opponent, result, accuracy, completion time, and Elo movement. Ranked records are read-only to protect ladder integrity.
  • The private Admin Control Lab now has instant player search, access/form/ranked filters, current-season Elo ratings, metal badges, W–L–D records, peaks, ladder positions, and a mobile-friendly player management panel.
  • Ranked now has a collapsible Metal Ladder — from Hydrogen placement through Iron, Copper, Silver, Gold, Platinum, Uranium, Osmium, and Iridium — with every badge presented as a premium ranked reward beside its Elo band.
  • The Chemistry Quiz, Ranked Duels, and Leaderboard now share one lab-notebook design. Mobile play puts the question first, run tickets summarise every practice setup, and controls are larger and keyboard-friendly.
  • 個 home page 全新設計 — 元素週期表式 Al 商標（A. Lam = 鋁，原子序 13）、實驗簿方格紙底、PHY／CHEM／BIO 顏色標籤，仲有 Ranked 金屬段位梯直接放上首頁。暑期課程資訊都更新埋。
  • Ranked 段位有靚 badge 喇 — 每個 tier 都係佢隻金屬嘅真實質感：啞面 Iron、暖銅 Cu、亮銀 Ag、金 Au、冰 Pt、發光鈾玻璃 U、重感藍 Os、同埋 Iridium 嘅七彩虹光（佢個名就係嚟自彩虹女神 Iris）。Placement 期係一片未成形嘅 Hydrogen 玻璃。
  • Ranked 題目而家同 casual quiz 一樣有顏色提示 — 橙 = 原子序、綠 = 名、紫 = symbol／化學式，一眼睇到條題問乜。
  • Ranked 對戰而家由 server 逐題派發、計時同核對。中途離開再返嚟會接住原本進度；答案同對錯等成場完結先一次過顯示。
  • New Ranked Duels — 10 題限時對決，與另一位玩家的 Ghost 挑戰同一組題目，以速度和準確度決勝。Elo 排位由 Iron → Copper → Silver → Gold → Platinum → Uranium → Osmium → Iridium，首 10 場為 Hydrogen placement；答案由伺服器核對。現已進入公開 Beta 測試。開始排位
  • Leaderboards now have an All-time / This season toggle — seasons run in school-year quarters (現時係 S0 Beta，9 月開 S1)，季尾排名鎖定，季初可以重新爬。
  • The quiz now accepts answers typed on a Chinese keyboard — fullwidth characters like ＳＯ３ count the same as SO3, so a right answer is never marked wrong because of the input method.
  • New 升中四 Physics One-Day 免費體驗課 page — 光學奇趣: a one-hour free trial of DSE-style physics thinking (大 n 細 n · 折射五式). One-tap 報名 + WhatsApp with the session times. See it
  • New 升 S.3 One-Day 免費體驗課 page — 選科揭秘＋元素故事記憶法。一小時了解中三物理／化學／生物課程地圖與選科方向。查看現在的教學示例
  • The home page is now a clean link hub — A. Lam's photo and bio up top, then one-tap buttons to the summer schedule, enrol, the chemistry quiz, the leaderboard, the members zone, and Instagram / Threads / WhatsApp. Your latest posts still appear below.
  • New 26–27 Summer Course Schedule page — all S.3 Science and S.4 Physics summer classes with timeslots, locations, and a week-at-a-glance view. View the schedule
  • New guide: does our F.4 Force & Motion course fit IGCSE / IAL / IB / AP students? A topic-by-topic comparison against the international physics syllabi. Read it
  • The Daily Challenge is now for signed-in players — log in or sign up (it's free) to play today's set and appear on the daily leaderboard.
