How to study for Grade 12 Maths (Paper 1 and Paper 2)

Updated October 2026 · 8 min read

Grade 12 Maths feels huge because it is: two papers, ten topics, three hours each. But the exam is more predictable than it looks. The Department of Basic Education publishes how many marks each topic is worth, and the same kinds of questions come back every year.

This guide shows you where the marks are, how to find your weak spots, and how to revise so that it actually sticks. It's written for Grade 12 learners, and for Grade 11s who want a head start.

If you're wondering how to pass matric Maths, or how to push your mark higher, the answer starts with knowing where the marks are.

Grade 12 Maths Paper 1 and Paper 2: the topics and marks

You write two papers. Each one is 3 hours and 150 marks. Here's how the marks are split, from the Department's own exam guidelines:

Two things jump out. In Paper 1, functions and calculus together are almost half the paper. In Paper 2, trigonometry alone is a third of it. If your time is short, those are the topics that pay back the most.

The questions also come at four levels. About 20% are straight recall (knowing a formula or a fact), 35% are routine questions like the ones you did in class, 30% are harder questions that join ideas together, and about 15% are unfamiliar problems. So most of the paper is made of question types you can practise. You don't have to be a genius to pass well; you have to be prepared.

Step 1: Use a past paper to find your weak topics

Most learners revise by starting at chapter one and working forward. That wastes time on what you already know.

Instead:

1. Write one past paper under exam conditions. Three hours, no notes, a calculator and the information sheet only.
2. Mark it honestly with the memo. Past papers and memos are free on the Department of Basic Education's website.
3. Write down every topic where you lost marks. Not "I got 52%", but "lost most of the calculus question, and the trig identities".

That list is your revision plan. Start with the topics that are worth a lot of marks and where you lost the most.

Remember that the final exam can draw on work from Grade 10 and 11 too, like factorising, exponents and basic graphs. If a Grade 12 topic keeps going wrong, the gap is often in that earlier work.

Step 2: Fix one topic at a time

For each weak topic, work through it in this order:

1. Understand it. Go back to the method and make sure you know why each step happens, not just the steps. If you can explain it out loud to someone else, you understand it.
2. Practise the standard questions. Do the routine ones until you can do them without looking at an example.
3. Do past paper questions on that topic only. Look up the same topic in several past papers and do just those questions. You'll start to see the patterns.
4. Check your mistakes. For every question you got wrong, write one line about what went wrong: a sign error, the wrong formula, a misread question.

Then move on. Don't try to perfect a topic before touching the next one. Coming back to it a week later helps it stick far better than doing it for hours in one go.

Step 3: Learn the parts you simply have to know

Some marks come down to memory: geometry proofs, the reasons you write next to each geometry statement, and the formulas that aren't on the information sheet. Ask your teacher exactly which ones you need, write them on one page, and go over that page for a few minutes every day. These are some of the easiest marks on the paper, so don't leave them to the night before.

Step 4: Write full past papers under exam conditions

In the last few weeks before the exam, switch from topic practice to full papers. Do at least two or three of each paper under real conditions. This builds the stamina to stay sharp for three hours and shows you where your time goes.

A useful guide: 3 hours for 150 marks is a little over a minute per mark. A 6-mark question should take about 7 minutes. If you're spending 20 minutes on it, move on and come back later.

Exam tips for Paper 1 and Paper 2

• Read through the whole paper first. Start with the question you're most sure of. It settles you and banks marks early.
• Show your working. Write down each step clearly. Your method is what the examiner follows.
• Keep going even if an earlier answer is wrong. The Department's marking rules say that if you get a value wrong in one part and use it correctly in the next part, the next part can still get full marks. So never leave a question blank because part (a) went badly.
• Cross out what you don't want marked. If you make two attempts at a question and don't cancel one, only your first attempt is marked, even if the second one is right.
• Don't make up values. Assuming an answer to get through a problem isn't accepted.
• Check your calculator mode. Use degrees for trigonometry, and only round your final answer, not the steps in between.
• Use the information sheet. It's there for a reason, so check it before you try to remember a formula.

Common mistakes in Grade 12 Maths exams

• Losing a minus sign when expanding brackets or moving terms across the equals sign.
• Rounding too early in finance or trig questions, so the final answer is off.
• Writing a geometry statement with no reason, or with a reason in your own words.
• Forgetting to check that an answer makes sense (a negative length, a probability above 1).
• Leaving calculus "for last" because it feels hard, then running out of time on 35 marks.
• Only reading the memo, instead of doing the question first.

A matric Maths revision timetable

Short, regular sessions beat long, rare ones. A simple pattern:

• On school days: 45 to 60 minutes of Maths, on one topic.
• On weekends: one longer session, either a full topic test or half a past paper.
• Every second week: one full past paper under exam conditions, marked the same day.

Put your weakest, highest-mark topics early in the week, when you're fresh.

How parents can help with matric Maths

You don't need to know any calculus to help. The most useful things are practical: a quiet place and a fixed time to work, a printed past paper and memo, and asking "which topic are you working on today, and how did the questions go?" instead of "have you studied?". If your child marks a past paper and shows you their list of weak topics, you'll both know exactly where the work needs to go.

Where our cheat sheets come in

Step 2 is where most learners get stuck. Past papers show you what you got wrong, but not why, and a textbook chapter is a lot to wade through the night before a test. That's exactly the gap our Grade 12 Maths cheat sheets are built for.

Each sheet takes one topic and breaks it down step by step, so you can fix just the part you're missing:

• Clear graphics on every page. Graphs, diagrams and sketches drawn for the topic, so you can see what's going on instead of just reading about it.
• Everything broken into small steps. One idea at a time, in plain words, with worked examples that show every line.
• "Before you start". The earlier work the topic needs, so a gap from Grade 10 or 11 doesn't trip you up.
• "The short version". The whole topic on one page, for quick revision before a test.
• "Common mistakes". The errors learners make in that topic, shown so you can spot them in your own work.
• "Before you move on". A checklist to run through after any question on the topic.

Find your weak topic in Step 1, open its cheat sheet in Step 2, then go back to the past paper questions. You can see how they work with a free one first.
