Seven PSLE decks, 160 questions
Five Science decks — one for each theme in the syllabus: Diversity, Cycles,
Systems, Interactions and Energy — that explain the ideas in plain language.
Alongside them, two question banks of fifty exam-style questions each, one
Maths and one Science.
The teaching decks and the question banks do different jobs on purpose. A card
that says "6" is a fine test question and a useless flashcard. So the Science
theme decks explain why, and the banks ask.
Why: we tried generating exam questions automatically first, and
it didn't work. What came out was one question repeated with different numbers —
twenty-five variations of the same cyclist travelling a different distance. It
looked like practice and taught almost nothing. These are written by hand instead.
What "By Versed" means
Decks we've made ourselves now carry a By Versed badge, and you can filter Explore
to show only those.
Why: the badge is a claim, so it should mean something specific.
Every Maths answer is recalculated by a separate program that never sees the
question — if the two disagree, the deck cannot be published. Science answers are
checked against the syllabus, including the parts it explicitly says are not
required, so a question can't stray past what your child is actually taught.
We wrote every question against the current MOE and SEAB documents rather than from
memory. That's how we noticed the Maths syllabus now covers Rate at
P5, where a lot of older material still teaches Speed. Every question is original —
past papers belong to SEAB and are not ours to reuse.
Decks that keep up
When we add questions to one of our decks, anyone who already has it now sees how
many are new and can pull them in with one tap. Your existing cards, and everything
the app has learned about how well you know them, stay exactly as they are.
Why: adding a deck takes a copy, so it used to be frozen on the day
you got it. We doubled both question banks and it reached nobody — the only way to
get the new questions was to delete the deck and add it again, losing every bit of
progress. Now you keep the progress and get the questions.
Study notes now actually appear
AI study notes were being generated correctly and then displayed as an empty box.
They render properly now, and they no longer need a connection to do it.
Why it went unnoticed for six months: the Download button worked the
whole time. Anyone checking the feature by saving a file got a complete, correct
document and would have concluded it was fine. Only reading the notes on screen
showed the problem. We're sorry — that's a paid feature, and it was broken for a
long time.
