GCSE Maths OCR Paper 1: last-minute revision

Paper 1 is calculator, 1 hour 30 minutes, 100 marks. You have 3 days, here is where the marks are.

OCR J560
The plan

Your 3-day plan

One focus per day, building to a timed run. Work it in order.

3
3 days to go

Multi-step calculator questions and formula recall, OCR gives you less on the formula sheet than you might expect

  • Work through compound interest, reverse percentages, and speed/distance/time questions. All appear on almost every calculator paper
  • Memorise the circle area and circumference formulae properly, OCR's formula sheet does not cover every formula AQA gives you, so check what you actually need to recall
  • Practise 3 scatter graph questions: plotting, drawing the line of best fit, and reading off predictions
2
2 days to go

Algebra you have to set up yourself

  • Work through simultaneous equations and quadratic sequences: both recur across OCR papers
  • Practise algebraic proof questions using 2n and 2n+1 notation for even and odd numbers
  • Do 5 gradient and y-intercept questions from y = mx + c. Read the equation, do not guess from a rough sketch

Light review, not new content

  • Re-read your circle theorem names and which angle facts justify them. You need to name the reason, not just get the number
  • Skim the OCR formula sheet one more time so you know exactly what is and is not given
  • Get an early night. Paper 1 rewards a clear head more than any last-minute cramming
Priority order

The topics that come up most

Ranked from analysed past papers. Start at the top: if you run out of time, you will have covered the most-tested ground.

1

Circle Theorems

A very high-frequency geometry topic. OCR questions on circle theorems are often multi-part and can be worth 5-7 marks in a single question

2

Simultaneous Equations

Tested across OCR papers. Always worth setting up algebraically with clear working, never worth guessing an answer

3

Vectors

Higher tier only. Consistently a multi-part question worth 6-7 marks on OCR papers, usually a geometric proof using column vectors

4

Standard Form

High frequency across the whole spec. On a calculator paper, expect standard form entered correctly into your calculator and read back off the display accurately

5

Reverse Percentages

A high-frequency calculator topic. Finding the original amount before a percentage change, not just calculating the new amount

6

Speed, Distance, Time

Appears on calculator papers most series, often combined with unit conversion. Set up the formula triangle before you calculate

7

Quadratic Sequences

Higher tier only. Find the nth term of a quadratic sequence, a topic OCR tests as reliably as the other boards

8

Algebraic Proof

Appears most series. Use 2n for even, 2n+1 for odd, and show every algebraic step, OCR mark schemes award credit for the steps as much as the conclusion

Your Knowledge Organisers

PrepWise has a one-page Knowledge Organiser for every topic above. In the final 3 days, use them the same way each time: cover the page, try to recall the method and a worked example from memory, check what you missed, then repeat the next day.

Exam technique

Rules specific to Paper 1. On this paper, structure earns as many marks as knowledge.

1

Show your working, every time

Method marks are your safety net even on a calculator paper. If your final answer is wrong but the examiner can see a correct method (correct formula, correct substitution, correct rearrangement), you still pick up marks. A right answer with no working can lose marks under OCR's mark scheme too.

2

Know what is on OCR's formula sheet, and what is not

OCR provides a formula sheet on every paper, but do not assume it matches AQA's list exactly. Check the formula sheet in a recent past paper before the exam so you are not caught recalling something that was given, or missing something you needed to know.

3

Don't round until the final line

Keep the full calculator display (or at least 4-5 significant figures) between steps in a multi-step problem and only round your final answer to the accuracy asked for. Rounding after step one and carrying that rounded figure into step two is the most common accuracy-mark loss on a calculator paper.

4

Check your calculator is in degrees mode before any trigonometry question

A calculator left in radians mode gives completely wrong answers to SOH CAH TOA, sine rule, and cosine rule questions, and the error is easy to miss because the calculator still produces a number. Check the mode indicator before your first trig question, not after you get a strange answer.

5

Write the calculation down before you press any buttons

For a multi-step problem, write the formula and the substituted values on paper first, then use the calculator to evaluate. This protects your method marks if you mistype a number, and it stops you losing track of what you are calculating and why.

Avoid these

5 mistakes that cost marks

The errors examiners see most on this paper. Each one is an easy mark you already know how to keep.

Rounding a calculator answer too early in a multi-step problemKeep the unrounded value on your calculator display and carry it into the next step. Only round the final answer to the degree of accuracy the question asks for

Naming the wrong circle theorem, or giving no reason at allLearn the exact wording for each theorem: 'angle in a semicircle is 90 degrees', 'tangent meets radius at 90 degrees', and write it down every time you use it

Leaving your calculator in radians mode for a trigonometry questionCheck the mode display shows 'D' or 'DEG' before starting any sin, cos, or tan calculation. A radians-mode answer looks like a normal number, so this error is easy to miss

Substituting into simultaneous equations incorrectly, especially with negative coefficientsWrite out the elimination or substitution step in full. Do not do the sign change in your head, it is the single most common place marks are lost

Assuming a formula is given on OCR's sheet when it is notCheck a recent OCR formula sheet before the exam. Do not assume every formula AQA gives you is also given by OCR, some need to be recalled from memory

Exam day

The morning of the exam

The 60 minutes before you walk in. Review what you know and settle your nerves.

  • Check your calculator has working batteries, and a spare set if you can manage it
  • Bring pen, pencil, ruler, protractor, compasses even on a calculator paper, geometry questions still need them
  • Skim the OCR formula sheet so you know exactly what is given and what you still need to recall
  • Check your calculator is set to degrees mode before you go in, this takes 10 seconds and prevents an entire trig question going wrong
  • Attempt every question, even partially. A method mark for a half-finished answer beats a blank box
  • Leave your last 5 minutes to check unanswered questions, not to redo ones you have already completed
