Will I find it hard?

Difficulty depends on your experience, interests, teaching and assessment. These are our reflection prompts, not an official difficulty rating.

• How do you feel about explaining a method and working through unfamiliar multi-step problems?
• Try the sample without looking at a worked answer, then check the steps you need to practise.

Does it scale up or down?

UAC Table A3 reports separate means for reported HSC marks and scaled marks per unit, with candidature for each course in 2025. These are cohort statistics. They do not supply individual raw exam marks or a conversion between the two columns. No exact course match is attached to this profile. Check the official report; do not infer a direction.

Scaling is not a measure of difficulty or a guaranteed bonus. Prioritise content you can engage with and required subjects for courses you are considering.

Formulas and equations

A formula is a rule that connects two or more quantities using pronumerals. When we know the values of every variable except one, we can find the missing value by substitution : replace each pronumeral with its number, then evaluate using the correct order of operations (brackets, then powers and roots, then multiplication and division from left to right, then addition and subtraction from left to right). Substitution works the same way whether the formula is linear (every variable appears to the power of one, such as P = 2l + 2w) or non-linear (a variable is squared, square-rooted or in a denominator, such as A = πr² or v = √(2gh)). Good habits make substitution reliable. First, write the formula down before you substitute, so a marker can follow your reasoning and award method marks. Second, place brackets around negative numbers when you substitute them, because −3² equals −9 but (−3)² equals 9. Third, check that all quantities are in compatible units before you substitute; a formula that expects metres will give nonsense if you put in centimetres. Fourth, only round at the final step and state the units of the answer. Sometimes the unknown is not the variable on its own on the left-hand side. In that case you can still substitute the known values first and then solve the resulting equation using inverse operations. For example, if v = u + at and you are given v, u and t, substitute them and then solve for a. This approach is often quicker in an exam than rearranging the formula first, and it is less prone to algebraic slips. Both methods are valid; choose the one you find most dependable. Formulas appear across the Standard course in contexts such as perimeter and area, simple interest, energy use, temperature conversion (F = 9C/5 + 32) and sport statistics. A calcu
