A-Level Biology 9700 Paper 5: Variables, Readings and Evaluation

Biology: planning and evaluation
This paper asks you to design a workable experiment and then judge what the given data supports. The answer shapes are fixed: independent variable, dependent variable, controlled variables, instrument precision, direction of error, improvement – each one a mark.
How is A-Level Biology 9700 Paper 5 assessed, and what does each part carry?
Paper 5 (Planning, Analysis and Evaluation): Planning + analysis, 30 marks (A Level 12%); Paper 4 (A Level Structured Questions): Structured questions, 100 marks (A Level 38.5%)

Assessment at a glance (2027)
| Component | Content | Weighting | Duration |
|---|---|---|---|
| Paper 5 (Planning, Analysis and Evaluation) | Planning + analysis, 30 marks | A Level 12% | 1 h 15 min |
| Paper 4 (A Level Structured Questions) | Structured questions, 100 marks | A Level 38.5% | 2 hours |
A-Level Biology Paper 5 drilling technique: plans need independent, dependent and controlled variables, sample size and repeats; data work uses rate = amount / time; evaluation covers random (repeats) and systematic (instrument) error. Percentage uncertainty = error / reading x 100%.
What each paper is actually testing
| Paper | Drill focus | How marks are lost |
|---|---|---|
| Paper 5 (Planning, Analysis and Evaluation) | variable control + statistical reasoning | Planning says measure growth but never names the instrument or the precision, so both scheme marks go. |
| Paper 4 (A Level Structured Questions) | AS + A2 content | Evaluation says there was error with no direction (too high or too low) and no improvement aimed at it. |

Drill order: by topic, then by year, then the mark scheme
| Step | What you do | Why |
|---|---|---|
| 1. By topic | Work through each topic, starting with the paper that allows least help (no calculator / closed book) | Exposes what is genuinely not understood |
| 2. By year | Whole papers to time, one or two a week | Trains pace, stamina and question selection |
| 3. Mark scheme | Go through the marking scheme question by question and log the scoring steps you missed | Most lost marks are written wrong, not thought wrong |
Should drilling go by topic first or by year?
By topic first, then whole papers by year, then the mark scheme. The first third of the time goes topic by topic (8-10 years of the same topic back to back), the middle switches to timed whole papers, and the last fortnight only redoes the recurring errors from your log.
A 12-week drilling timetable
| Week | Phase | What to do |
|---|---|---|
| Weeks 1-3 | By topic: foundation | Topic by topic, starting with the easiest marks, building habits and recall |
| Weeks 4-6 | By topic: core | 8-10 years of the same topic back to back, errors classified by topic |
| Weeks 7-8 | By topic: advanced and electives | Elective and higher-order topics, now under time pressure |
| Weeks 9-10 | By year: timed papers | One full paper a week, timed, no reference materials |
| Week 11 | Mark scheme work | Question by question against the marking scheme; list the scoring steps you omitted |
| Week 12 | Plug holes and simulate | Only the recurring errors from your log, then one full exam simulation |
Subject-specific weighting for this timetable: Weeks 1-3: planning only, always four sentences – what is changed, what is measured, what is held constant, and with which instrument to what precision.
Weeks 4-6: graphs and statistics, giving trend, then numbers, then which test applies and why.
Weeks 7-9: evaluation – one error, its direction, one matching improvement; rewrite if they do not line up.
Weeks 10-12: full papers to time, half the time on planning and half on evaluation.
Use it properly: this is not a checklist to finish. Every week must keep time for redoing errors, or from week 9 you will be repeating the same batch.
Pacing
| Paper | Time | Suggested split |
|---|---|---|
| Paper 5 (Planning, Analysis and Evaluation) | 1 h 15 min | about 37 min per question |
| Paper 4 (A Level Structured Questions) | 2 hours | about 12 min per question |
How should the time be split inside each A-Level Biology 9700 Paper 5 paper?
Paper 5 (Planning, Analysis and Evaluation): about 37 min per question; Paper 4 (A Level Structured Questions): about 12 min per question
The drilling mistakes that cost the most marks
| Mistake | What it looks like | What actually happens | Instead |
|---|---|---|---|
| Missing controls | Temperature only | List pH, concentration and volume as constant | controlled variables |
| Rate without units | Just 1 | Write 60 cm3/min | 60 cm3/min |
| Evaluation without remedy | Error noted only | Suggest repeats and better instruments | repeats + instruments |
The error log and the mark scheme
Three columns: the sentence as written, the scheme key words (independent, dependent, controlled, precision, direction, improvement), and which was missing. Put the most frequent gap on page one.
How many years should you drill?
Paper structure and syllabus content have changed, so older planning questions do not always match the current paper: build the four-sentence shape on three to five years of current papers, then use the official specimen and your own lab reports.
How many years of past papers is enough?
Paper structure and syllabus content have changed, so older planning questions do not always match the current paper: build the four-sentence shape on three to five years of current papers, then use the official specimen and your own lab reports.
Frequently asked questions
Is this page a mock paper or a drilling guide?
This is the A-Level Biology 9700 Paper 5 drilling guide: assessment structure, drill order, a 12-week timetable, pacing, common mark losses and the error-log method. For questions with answers, use the A-Level Biology 9700 Paper 5 mock papers linked under Related.
By topic or by year first?
By topic. Eight to ten years of the same topic back to back is what exposes repeating errors; going straight to whole papers just repeats the same batch under time pressure.
How should the error log be written?
Do not copy out questions. Per error record four things: question reference, which step failed (concept, wording, calculation), what the mark scheme requires, and the correct action next time.
How many controlled variables should be listed?
Only those you can say how to keep constant – usually three, each with a method. Ten names with no method earn one mark where three with methods earn more.
Does the choice of statistical test need a reason?
Yes: naming the test is one mark, giving the reason (comparing two means of continuous data) is the second, and it is the cheaper of the two.

Next step: find a tutor / register as a tutor
After drilling, the hard part is telling a conceptual error from a writing error. Tell us the year group, the school and your available times, and TutorZone will match you with a tutor who knows the HKEAA assessment requirements.
Demand for tutors in this subject is steady, and those who can explain the marking scheme and where marks are won are especially sought after. Register free; you pay only when a match succeeds.
