Why do you keep
Every wrong answer has a reason. Whyology tracks that reason — and makes sure you fix it, not just revisit it.

The real problem
Most students revise what they're comfortable with. The uncomfortable truth: the marks you're losing are almost always to mistakes you've already made before.
Re-reading chapters you already know
It feels productive. It rarely moves the score.
Seeing the same question type go wrong again
You noticed it once. You didn't fix the root cause.
Vague revision plans that drift away
"Revise Organic Chemistry this week" covers everything and fixes nothing.
How it works
Log the mistake in 15 seconds
Right after the test. Photo of the question. One tap for what went wrong. Done — built for post-exam exhaustion, not quiet study time.
Quick Capture — minimal by designProve you fixed it — don't just re-read it
When a mistake comes up for revision, the app asks you to recall the answer first — before showing your note. You prove you fixed it, not just that you remember logging it.
Active recall — not passive re-readingWatch it compound
Get it right — next revision in 2 days, then 4, then 8. Get it wrong — resets to tomorrow. After 6 months, a record of every mistake you've provably fixed.
Spaced repetition · No manual schedulingThe insight that makes step 2 work
Every mistake traces back to one of four root causes. The app asks you to pick one when you log. That single tap changes what your revision looks like — and what you need to do to actually fix it.
I Didn't Know
No memory of this concept at all.
→ Go back to source material first. Revising something you never learned doesn't work.
I Knew but Forgot
Studied it. Memory failed under exam conditions.
→ Recall practice — write it from memory before the app shows your note.
I Knew but Slipped
Had the knowledge. Execution failed — wrong formula, sign error, misread.
→ Solve a similar question under time pressure. Not theory. Execution.
I Panicked or Guessed
Time pressure overrode what you knew.
→ Test strategy — set your rule for when to attempt and when to skip.
See it in action
This is what step 2 looks like
A "Knew but Slipped" mistake comes up for revision. The app doesn't show the note first — it asks you to recall first.

Your revision prompt
Write the correct sign convention for a convex lens from memory — before looking at your note.
The gap between a seat and missing it is often under 30 marks. That's the difference this app is built to close.

Why annual only?
The product only works if you use it for months. Annual billing creates the commitment that makes the habit stick.
I already have a coaching class.
Coaching teaches new concepts. Whyology fixes the ones you already know but keep getting wrong in the exam. Different problem.
What if I don't see results?
The app works on data you log. Log consistently for 6 weeks and check revisions daily — you will see the pattern.
