Blurting Shows What You Remembered, Not What You Left Out

Mocks start in three weeks. You've done what everyone online recommends. You took a blank page, wrote "Cell transport" at the top, and blurted everything you could remember for ten minutes: diffusion, osmosis, active transport, something about water potential. Then you opened your notes to check, and it took twenty minutes. Half of it was deciding whether "kind of mentioned it" counts.

Blurting is a good method. It's active recall, and active recall beats rereading. But it has a blind spot.

The blind spot: you can't blurt what you forgot existed

A blurt shows what came out of your head. It doesn't show what should have come out. To find that, you go through your notes line by line and compare, which is slow, and it's easy to be generous with yourself at 10pm.

Two more problems come up later:

• The gaps don't come back. You notice you left out co-transport. You highlight it, close the notebook, and nothing makes you revisit it in three days, which is exactly when spacing says you should.
• Remembering a fact isn't applying it. A-level questions rarely say "define water potential". They give you a potato cylinder in a sucrose solution and ask what happens to its mass. A blurt tests the first skill, not the second.

Keep blurting. Add a check that covers everything

The fix isn't to stop blurting. It's to follow each blurt with a check that covers every point in the topic, including the ones you forgot existed.

1. Blurt first, on paper. Ten minutes, as usual. This part is free.

2. Upload the same topic's notes to Tali. Your class notes, the teacher's revision PDF, or photos of your textbook pages all work. Tali splits them into short notes, one point each, and writes multiple-choice and fill-in-the-blank questions for every point. Not just the ones you happened to remember.

For example (illustrative; the wording follows your notes):

Note · Water potential
Water moves from higher (less negative) to lower (more negative) water potential. Adding solute lowers water potential.

Question · A potato cylinder is placed in a sucrose solution with a lower water potential than its cells. Its mass will:
A. increase B. decrease C. stay the same D. double → B

3. Compare. Any point you blurted but got wrong in the questions is a misunderstanding. Any point you didn't blurt and got wrong is a gap you didn't know about. That second group is the one blurting alone can't show you.

4. Let the misses come back on their own. Wrong answers go into a review queue. They come back tomorrow, then at longer gaps each time you get them right, and back to tomorrow if you miss again. When you tap Practice, due reviews always come first.

5. Check from a second angle. A point only counts as mastered after you get it right two different ways. "Test me on a new scenario" on the readiness page writes a fresh question that puts the same idea in a new situation, which is much closer to an exam question than a definition is. Points you got right once but missed when the question changed go into their own group, "False confidence". Revise those first.

Prefer saying it out loud? Voice mode is blurting with someone listening. Explain the topic as if you were teaching it, and the tutor asks follow-up questions and checks your answers against your notes. Spoken answers count the same as typed ones.

A three-week rhythm before mocks

When	What
Start of each session (10 min)	Practice: clear due reviews
One topic a day	Blurt on paper → upload or practise that topic → note what you left out
Every few days	Readiness page: work through "False confidence" with new scenarios
Week of mocks	Only the "False confidence" and "Known gap" groups

If you set your mock date, the readiness page gives you a daily target: points not yet mastered ÷ days left.

What it costs

• Free test, no account: upload one text-based PDF and get ten multiple-choice questions written from it, with an answer review at the end. One a day, and your file isn't saved.
• Account: 15 free credits on sign-up, no card. 1 credit = one uploaded file (up to 20 sections, about 16,000 characters). That covers notes, all questions, unlimited practice and reviews.
• Chat: 1 credit per 12 messages. Voice: 1 credit per 2 minutes of clock time. Fifteen credits is only about half an hour of talking, so type most explanations and save voice for the topics you really can't articulate yet.
• After that: $20 for 45 credits (prices are in US dollars, and credits don't expire).

Limits: Tali only asks about what's in the notes you upload, so if your notes skip part of the spec, so will the questions. It doesn't mark long-answer exam questions the way an examiner would, and it can't promise a grade. Keep doing past papers for that.

Try it on tonight's topic

Do your usual blurt on one topic. Then put that topic's notes through the free ten-question test (no account needed) and count how many misses were things you never wrote down.
