A mock test only works if the misses come back.
Sitting a full-length paper under time is the single best way to find out what you can't do yet. What you do with the wrong answers over the next two weeks is what actually changes the grade.
What makes a mock test a mock test
A worksheet you pause halfway through is revision. A mock is the whole paper, in one sitting, with a clock. Keep these four and the result means something:
- Full length, one sitting. Same number of questions and same minutes as the real exam.
- Closed book. Notes and phone in another room. Looking things up turns the diagnosis into fiction.
- Answer everything. A guess you flag is data. A blank is not.
- Mark honestly. "I basically had that" is the most expensive sentence in exam prep.
Sort every miss into one of three piles
Most students re-read the mark scheme, nod, and move on. That fixes nothing, because the three kinds of wrong answer need three different fixes.
- Didn't know the method. This is a real gap. It becomes a practice topic and needs to reappear on later days, not just tonight.
- Knew it, slipped. Sign error, misread units, copied the wrong number. Fix with a checking rule, not more theory.
- Ran out of time. A pacing problem. Set a per-question budget and practise skipping early.
Write the reason next to each question in your own words. "Forgot to flip the inequality when dividing by a negative" is a fixable thing. "Algebra" is not.
Three weeks, two mocks, short nights in between
Sit mock one cold, whatever the score looks like. Review it the same day while you still remember your reasoning. Name every miss and save it.
Short sessions, not marathons. Work only the named misses, then stop. A miss you got right today should reappear a few days later, not tomorrow — that spacing is what makes it stay.
Sit mock two on a different paper. Compare the reasons, not the scores: the question to answer is whether last month's method gaps are still method gaps.
In the last 48 hours before the exam, no new mocks. Re-work the misses you got wrong twice and sleep.
The in-between nights are the part we run for you
You can sit a real timed mock in the app — question by question, flag what you're unsure of, leave and come back without losing your place, and get a score worked out on the server rather than self-marked.
Every miss is then saved by name and scheduled. Today's Practice hands you a small set of the things you actually got wrong, spaced further apart each time you get one right. When the set is finished, the night ends — You're done for today. No streak to protect, no points, nothing to keep you scrolling.
If a topic keeps returning and you don't need it, skip it and it stops coming back.
How should I use a mock test to study?
Sit the full paper under real time with no notes, then review it question by question and label each miss as a method gap, a slip, or a timing problem. Turn the method gaps into named practice items and work a few of them each night, spacing the ones you get right further apart, and re-test with a second full mock about two weeks later. LemonSugar Ai does the bookkeeping: timed mock exams with server-scored results, every miss saved in plain language, and a short returning set in Today's Practice that ends with You're done for today.
Start with tonight's missed questions.
Today's Practice is a small set drawn from what you got wrong — and it finishes.
