Combine classes

Students, roster names and practice sets all move into the class you keep. The ones you merge in are archived, not deleted — bring any of them back below if you change your mind.

Add roster usernames

Roster names are invites: the student must open Sign up once and enter this class's code to set their own password before they can log in.

Add a student with a password

Creates a ready-to-use account — no sign-up needed. Give the student the username & password below and they can log in straight away.

Question sets

★ Supersets

You write the same five kinds of question in every topic set. A superset pools one kind across all of them and remixes the pieces — a matching question whose five pairs come from three different sets is harder and fairer than any of the three, because the topic stops giving the answer away. Built supersets are ordinary sets: assign, edit and practise them as usual. They keep for 3 months, then you download them and they leave the site.

Find duplicates

Looks through your questions for ones you have written more than once. A shared instruction over different maths, different numbers or a different answer is left alone — that's a variant you wrote on purpose, not a duplicate.

Import / export

Quizizz-style CSV — Download template shows one example row of every question type. Nothing is written until you've seen what's in the file: Import reads it, checks it against your bank and shows you the result first.

Import from Quizizz / Wayground

Paste quiz links (one per line) — each quiz becomes a set named after its title, timers and answer explanations included. The quiz must be publicly visible (not private). Fill-in-the-blank, drag & drop, dropdown, matching and multiple-choice convert automatically; anything else is listed below so nothing goes missing. Re-importing the same quiz adds duplicate questions.

Homework

Pick a class to see its latest homework and set new work. New homework goes to this class; its question sets are the ones this class can practise.

New homework

Every class and student practising right now — students appear within a few seconds of starting a round. Pause one student, one class, or everyone. Auto-refreshes.

Temporary account

Works until it expires, then login is refused — its data is kept.

⏳ Countdown (release a set to a class on a timer)

Schedule a set to unlock for one class when the countdown hits zero — so you can pace each class differently. Until then that class's students can't see or draw it. Picking a class here also grants the set to them.

Practice sets

Pick a class, then tick the question sets it can practise.

Appearance

Pick a colour scheme for you and your students. Auto follows the calendar: Merdeka around 31 August 🇲🇾, Halloween around 31 October 🎃, and Christmas through December 🎄.

🎨 Colour schemes (build your own palettes)

Recolour the whole site: pick a part, dial in its RGB colour, and this screen previews it live (students see nothing until you release a scheme). Save as many named schemes as you like. Each one is Hidden until you change it: Listed puts it in the Paw-n Shop at a price, Free quietly drops it into every student's picker — students are never told which is which.

🐛 Bug reports — checking…

Questions students flagged with the 🐛 button. Fix the question in the bank, then delete the report — the question's 🐛 count drops with it.

Students, log-ins & violations (counts: last 7 days) keys

Click a student to pick them up, then use the keys — or the buttons on the right. The 🔑 opens their log-ins, how long they were online and their violations, with ✕ to remove entries.

🐾 Bobby's Paw-n Shop (the ₱ store)

Add things students can spend Pawllars on. Set a price and a thumbnail; leave the release date blank to show it now, or set one to unlock it later. Before release an item is hidden — tick silhouette to tease its shape instead.

🎵 Music (tracks students play while they practise)

Drop an MP3 below, then open Mix to crop it, fade it in and out, set its volume and choose the break between loops. Save final version is what students hear — the original file is kept untouched, so you can re-cut a track any time. Each track is Hidden until you change it: Listed puts it in the Paw-n Shop at a price, Free quietly drops it into every student's picker.

Practice backgrounds (moving scenes behind questions)

Students pick one of the shown scenes before a round; the question panel darkens so the scene never fights the text. Two animated scenes are built in — add your own with short looping videos or animated images. Videos are kept at full quality.

AVI and WMV can’t be read by web browsers — export those as MP4 (H.264) first.

One entry per student — their week's running total. ✕ removes a student's week; to adjust marks use Students → Review.

🏅 All-time best (top 50 weekly scores)

A week's total joins the board when it beats the lowest record, and stays until pushed out by higher ones. ✎ changes a score, ✕ removes it.

🖼️ Save every picture on a page

For the sites with old Maths questions saved as images. Paste the address of the page, pick which ones you want, and they are written straight into a folder you choose — G:\Bobby Belajar\bobby belajar downloads the first time, then remembered.

If a site won't show its pictures, right-click one → Copy image address and paste that instead: when the address ends in a number (…/2009/Pic40.gif) the whole set is fetched, Pic1 onwards.

🔔 Notifications

Pop-up messages students see at chosen moments. The 3-day-streak login congratulation is built in — add your own Log-in (3-day streak+) message to reword it. {streak} becomes the student's streak.

Chance is how often it fires. You can give one when several different notifications — add them one at a time and Bobby picks one at random by their chances, as long as that when's chances add up to 100% or less. Anything left over shows nothing.

📱 Phone reminders (they arrive even when Bobby Belajar is closed)

A student only gets these once they've turned them on in their own ⚙️ Settings — on an iPhone or iPad they must add Bobby to the Home Screen first.

Use {sub} {name} {streak} {days} {rival} {rank} {hw} in a wording and Bobby fills them in. Give one reminder several wordings and it picks a different one each time — never the same as last night.

📒 Reminders actually sent (the last 7 days)

One line per reminder that left BB, newest first. Sent means the phone's push service accepted it for delivery — if a student still saw nothing, the problem is on the phone (notifications switched off for Bobby, battery saver, or on an iPhone the app not added to the Home Screen). Failed means it never got that far. The wording shown is the one Bobby picked, as you typed it — {hw} and friends were filled in on the phone, not left as braces.

📐 Diagram builder (figures for maths questions)

Draw a figure out of rectangles, label its lengths — as numbers (33 cm) or as unknowns (10x cm) — letter its corners, and attach it to a question. Everything runs in your browser. A figure you save here can be re-opened and nudged, so a second question with different numbers is a minute's work rather than a re-draw. The same figure downloads as a PNG at printed-worksheet weights.

🧰 PDF → CSV converter (Economics Paper 1)

Drop Economics Paper 1 PDFs below (up to 5 at once). Everything runs in your browser: questions are read out, tables and diagrams are cropped automatically, and images are uploaded when you export. Type each paper's answer key (the question paper doesn't contain answers), name the set, and export — the CSV imports at Question bank ▸ Import / export. How it decides (guide, .md)

🔍 Workings to look at

Everything the marker was unsure about. A right answer whose working doesn't support it is the one worth your time — that is the calculator or AI tell. Anything it simply couldn't read is here too, and those students were let through, which is why a person has to look.

✏️ Working pad (for every student)

How thick the pen draws on the maths working pad. A stylus still goes thin-to-thick within whatever you pick — this scales the whole range, so handwriting still looks like handwriting. Students see the change on their next round.

What students see in their progress tab

When a student opens My progress and taps a set, they get the questions they answered wrongly. Tick a box and the question comes back whole — its options, its word bank, its picture — so they can actually work through it again. Untick it and they get the prompt and the answer only.

Nothing here reveals anything new: every question in that list was already answered wrongly, so its correct answer was shown at the time, and its options and diagram were on screen throughout the attempt. Your answer keys are never affected.
