How to Mark Your Child Past Paper at Home Without Being a Teacher

Plenty of families do past papers. Far fewer mark them properly, and the marking is where almost all of the benefit sits. An unmarked paper is an hour spent confirming what your child already knew.

The usual reason is reasonable. Parents feel unqualified to mark a Grade 9 Integrated Science answer. But marking a practice paper at home is not the same job as marking a national assessment, and the parts that matter most need no subject expertise at all.

Mark in three passes

The first two passes require nothing but attention, and in most papers they account for a large share of recoverable marks.

Pass one: what was left blank

Go through and circle every unanswered question. Then ask one question about each: was it skipped because it was hard, or because you ran out of time?

Those are completely different problems. Hard means revise the topic. Ran out means fix pacing, which is usually about spending too long early in the paper. A child with five blanks at the end has a timing problem and no amount of content revision will fix it.

In multiple choice papers there is no negative marking, so a blank is always worse than a guess. If you find blanks in a KPSEA practice paper, that alone is worth several marks.

Pass two: presentation

Without knowing any science or mathematics, you can check:

• Is there working, or only an answer? In KJSEA Mathematics 903, structured questions carry 80 of the 100 marks and method is credited separately.
• Do quantities carry units? Units are often a mark on their own.
• Is the work under the question, or scattered in margins where a marker may miss it?
• Can you read it? If you cannot, a marker working at speed may not either.

Pass three: accuracy, with the answers beside you

Now mark right and wrong against the answer booklet. Two rules make this far more useful:

Do not award all or nothing. If a question is worth 4 marks and your child got the method right but slipped on arithmetic, that is not zero. Real markers award method marks and follow through. Marking harshly at home teaches children that a small slip ruins a question, which encourages them to rub out correct work.

Write why, not just wrong. A cross teaches nothing. Two words in the margin, such as "no units" or "did not read question", teaches a lot.

The part that actually moves marks

When marking is finished, do not file the paper. Take the wrong answers and sort them into three piles:

Most children have far more careless marks than they believe, and careless marks are the cheapest to recover. A child who converts half their careless errors gains more than one who learns a whole new topic.

Then redo the paper

A week later, have your child redo only the questions they got wrong. Not the whole paper. If they now get them right, the correction worked. If not, the topic needs teaching rather than repeating.

Our guide to reading a KJSEA and KPSEA marking scheme explains how marks are split inside a single question, which makes the accuracy pass much less of a guess. How mock papers lift grades covers why timed whole papers beat loose questions.

If you need papers with answers kept separate so a child cannot see them while working, the KJSEA Complete Revision Course and the KPSEA Complete Revision Course both ship the answers as a separate booklet for exactly this reason.

You do not need to understand the subject to be useful here. You need to notice what is missing, and ask why.
