Turning past-paper practice into marks

It is possible to work through a stack of past papers and see your mark barely move. The papers are not the problem, the missing step is the loop that turns each attempt into a change in what you do next.

This guide sets out that loop: how to score a paper honestly against the way Add Math is marked, how to sort the marks you lost by their real cause rather than by topic, how to spend your limited study time on the loss that costs the most marks first, and how to re-test the same skill so you can see the gain. Done this way, practice stops being an activity you complete and becomes a measurement that steadily lifts your mark.

Marking is analytic, which means method marks are awarded stage by stage. That single fact is what makes the loop work: because marks live in the steps, you can see exactly where each one was won or lost and act on it.

1. 1

   Score honestly against the method

   Mark your own script the way a marker would, giving credit for each correct step, not just the final answer. A right answer with missing working and a wrong answer with sound working both tell you something you need to know.

2. 2

   Sort each lost mark by cause

   For every mark you did not get, write one word: concept, method, arithmetic, presentation, or timing. Do not sort by topic, two 'differentiation' losses can have completely different causes and completely different fixes.

3. 3

   Rank the causes by mark cost

   Add up the marks lost under each cause across the paper. The biggest total is where an hour of work buys you the most marks, start there, not with whatever topic feels least comfortable.

4. 4

   Rehearse the fix, then re-test

   Drill the exact skill behind the biggest loss on a few short questions, then re-attempt a question of that shape under timing. If the mark comes back, the loop closed; if not, your fix was aimed at the wrong cause.

Most students lump every slip together as 'careless'. Separating the causes is what tells you what to actually do differently, because each cause has a different fix.

• Concept: you did not know the idea or the rule. The fix is learning, not more papers, go back to that subtopic before you drill it.
• Method: you knew the idea but chose the wrong route or missed a step in the standard working. The fix is rehearsing the steps of that method until the sequence is automatic.
• Arithmetic: the method was right but a number went wrong. The fix is slowing the risky lines, sign changes, fractions, substitutions, and checking them, not re-learning the topic.
• Presentation: the mathematics was right but the working was too cramped or jumped steps, so method marks were not visible to award. The fix is laying working out one clean line at a time.
• Timing: you could do it but ran out of clock. The fix is pacing and question order, not the topic at all, see our timing guide.

The loop only pays off if you can see it working, so measure the same skill twice, before and after your fix.

1. 1

   Note the mark you lost

   Before you fix anything, write down the exact marks lost to the target cause on this paper, for example, four marks lost to sign errors in differentiation. That number is your baseline.

2. 2

   Do the focused work

   Rehearse the specific fix on a small set of questions of the same shape, keeping your working clean so you can see whether the fix is holding.

3. 3

   Re-test under the same conditions

   Re-attempt a fresh question of that shape under timing, then score it the same honest way. Compare the marks lost to the same cause against your baseline.

4. 4

   Bank it or repeat it

   If the loss shrank, the skill is improving, move to the next-biggest cause. If it did not, your fix was aimed wrong; re-check the cause and try a different fix rather than doing more of the same.

The hardest part of this loop is honesty: it is easy to mark your own answer generously, to call every loss 'careless', and to practise the topic you enjoy rather than the cause that costs the most marks. In our one-to-one sessions we score your papers the way a marker does, name the real cause of each lost mark with you, and rank them so you always know the single most valuable thing to work on next.

Then we set focused practice around that cause and re-test it, so you can see your marks move rather than hope they will. The result is study time spent where it pays, and a mark that climbs for reasons you can name.
