How to use the SPM Add Math formula sheet

Both Add Math papers come with a printed formula list you can turn to during the exam, 24 formulas in total, grouped by topic area, that you are allowed to look up rather than hold in memory. Knowing what is actually on that list, and where, is worth more than most students realise, because it changes how you prepare: some results you drill until they're automatic, and others you simply need to know how to find quickly.

• Algebra, the quadratic formula, the change-of-base rule for logarithms, and the n-th term and sum formulas for arithmetic and geometric progressions.
• Statistics, the standard (z) score, binomial probability, permutations, combinations, and the price index and composite index formulas.
• Trigonometry, the Pythagorean identity and its two related identities, the sum and difference formulas, and the double angle formulas.
• Geometry, the sine rule, the cosine rule, and the area of a triangle using two sides and the included angle.

The formula list only helps you if you can find the right line fast. Paper 1 gives you 2 hours for 80 marks across Sections A and B; Paper 2 gives you 2 hours 30 minutes for 100 marks across Sections A, B and C.

There is no Paper 3. Both papers move quickly enough that flipping back and forth through the list, reading every line to find the one you need, eats into time you could be spending on working.

• Get familiar enough with the layout that you have a rough sense of where each topic group sits, algebra near the top, trigonometry and geometry toward the bottom.
• Practise scanning by shape before you scan by words, a fraction with a square root under it looks different from a sum of sines, and your eye can find that shape faster than it can read a label.
• Write the formula down first, exactly as given, before you substitute anything. This is also a scorable step under analytic marking, and it stops you carrying across a mis-copied sign.

Most of the marks lost around the formula list are not about knowing the mathematics, they are about handling the sheet under pressure. A few patterns show up again and again.

• Grabbing a formula that looks similar without checking it fits the situation, reaching for the sine rule when the question actually gives two sides and the included angle, which calls for the cosine rule instead.
• Copying it down wrong, dropping a sign, swapping a subscript, or missing the plus-or-minus in a formula like the quadratic formula, then carrying that error through the whole solution.
• Not checking what each symbol means in context, for instance in binomial probability, mixing up which value is $p$ (success) and which is $q$ (failure), when the list itself states $p+q=1$.
• Only ever using the list in an open-book way during practice, so the exam is the first time it's read under a clock, which makes the whole page feel unfamiliar.

Here is an original question in the exam's style, showing how to move from the question wording to the correct formula on the list.

The goal is not to memorise the list, it is given to you precisely so you do not have to, but to reach exam day already comfortable with it, so nothing on the page is a surprise.

• When you practise past-style questions, always write out the formula you used from the list, in full, even if you already know it. This builds the habit the exam rewards.
• Time yourself locating a formula you have not needed in a while. If it takes longer than a few seconds, that group is worth another pass.
• Keep a simple personal note of which situations call for which formula, sine rule versus cosine rule, permutations versus combinations, since choosing the right one is the actual skill, not recalling the formula itself.

By the time exam day arrives, the formula list should feel like a tool you already know how to use, not a page you are meeting for the first time.

Watching a student use the formula list in real time is one of the fastest ways to see where marks are quietly being lost, a formula grabbed too quickly, a sign copied wrong, a substitution that skips a line an examiner would want to see. A teacher working one-to-one can sit with your working and point out exactly that, question by question, until using the list becomes second nature rather than a scramble.

Our teachers are experienced; lessons are taught online, in English, while the SPM papers themselves are set bilingually in Bahasa Melayu and English.

If you would like to see how this works with your own practice questions, a one-hour paid trial class, at the teacher's own rate, from RM50 per hour depending on experience, is a reasonable way to start. We won't promise a grade, but a closer look at how you handle the formula list is often enough to recover marks you were already close to earning.
