Explain how the process of mitosis ensures that daughter cells are genetically identical to the parent cell.
- DNA replication (S phase): Awarded — correctly states DNA is copied before division.
- Chromosome alignment: Awarded — chromosomes aligning at the metaphase plate.
- Spindle fibres: Missed — no mention of spindle fibres pulling sister chromatids apart.
- Cytokinesis: Missed — cell membrane pinching to produce two separate cells.
Not just a score — a lesson
Every extended answer is evaluated against the mark scheme written for that question, point by point.
Know exactly which mark points you hit and which you missed — not just a total out of 6.
AI explains what a full-marks answer would have included and gives you the precise language the examiner expects.
Hand the paper in and it goes straight to marking, answer by answer — no waiting days for a teacher to get to it.
Each written answer is scored point by point against the mark scheme for that question, and anything the marker is unsure about is flagged for review.
- Pancreas detects rise: Awarded — pancreas correctly identified as detector organ.
- Insulin released: Awarded — correct hormone named.
- Cells absorb glucose: Awarded — effect of insulin on body cells stated.
- Glycogen storage in liver: Awarded — glucose→glycogen conversion mentioned.
- Beta cells: Missed — should specify that beta cells in the islets of Langerhans secrete insulin.
- Negative feedback: Missed — no mention of the negative feedback mechanism maintaining homeostasis.
Two ways to revise, and they do different jobs
Every plan includes both. Mocks tell you where you stand; practice is how you close the gap. Most students sit one mock a week and practise in between.
The real thing, under exam conditions
A full paper against the clock, marked like the real one. This is how you find out where you actually stand.
- Timed, like the real paper — the clock runs and the paper submits itself when it reaches zero
- Marked by the AI examiner, mark point by mark point, the moment you submit
- Scored, with a breakdown of the topics that cost you marks
- One per subject per week, so each one still means something
Learn the mark scheme, no clock
The same exam questions with the timer off and the mark scheme open. This is the part you do between mocks.
- No timer — stop whenever you like and pick up where you left off
- Reveal the mark scheme on any question and see what full marks needed
- Not scored, and it never uses up your weekly mock
- Unlimited, and you can narrow it to a single topic
During your 7-day free trial you get one full mock — and practice stays unlimited the whole way through.
Currently available for AQA-aligned GCSE Triple Science: Biology, Chemistry and Physics for Higher Tier. More exam boards coming, including Edexcel.
