1. What is the exact value of the integral from 0 to 2 of (3x2 - 2x) dx?
An antiderivative is x3 - x2. Evaluating from 0 to 2 gives 8 - 4 = 4.
Use Skill Align for ACT Year 12 Mathematical Methods practice questions after the relevant topic has been taught. Students can start with the pathway demo, then practise by topic and mode.
ACT Year 12 Mathematical Methods includes 24 practice skills across Functions and relations, Calculus and rates of change, Probability and statistics, and Graphs and transformations.
A practice skill is a focused topic or question type designed to help students practise one curriculum-aligned concept with instant feedback and explanations. Skill Align uses practice skills to organise questions by year level, subject, strand, and curriculum focus.
These sample questions are visible on the page before login. They show ACT BSSS Year 12 Mathematical Methods functions, calculus, probability, modelling, and statistics explanations before opening the demo.
An antiderivative is x3 - x2. Evaluating from 0 to 2 gives 8 - 4 = 4.
Using the chain rule, f'(x) = 2x/(x2 + 1). At x = 2, f'(2) = 4/5.
Set 800 = 1200/(1 + 5e-0.4t), so 1 + 5e-0.4t = 3/2. Hence e-0.4t = 0.1 and t = ln(10)/0.4 = (5 ln 10)/2.
The unscaled total area is the integral from 0 to 3 of 2x + 1, which is 12. The unscaled area from 2 to 3 is 6, so P(X > 2) = 6/12 = 1/2.
The two values are one standard deviation below and above the mean. The mean is (58 + 74)/2 = 66, and the standard deviation is 74 - 66 = 8.
Set 3e0.5x - 2 = 10, so e0.5x = 4. Taking logarithms gives 0.5x = ln 4, hence x = 2 ln 4 = 4 ln 2.
ACT BSSS Year 12 Mathematical Methods practice should make functions, calculus, probability, modelling, and statistics feel structured rather than guessable. These examples preview that style before the no-login Mathematical Methods demo.
Mathematical Methods practice sits inside ACT BSSS Year 12 mathematics planning coverage across Essential Mathematics, Mathematical Applications, Mathematical Methods, Specialist Methods, Specialist Mathematics, algebra, calculus, statistics, probability, finance, and modelling, with Skill Align keeping the route focused on the selected maths pathway.
Senior practice is organised by pathway, unit, topic, and mode so students can revise targeted areas rather than sitting a full-paper workflow every time.
Start with the public sample questions to check the question style, then use the curriculum coverage page to choose a topic that matches the student's current classwork.
These examples are not the full topic list. Use the curriculum coverage page for the complete mapped pathway.
ACT students studying Mathematical Methods.
Yes. Public sample pages let visitors preview curated Skill Align questions without creating a saved student test record.
No. Skill Align is designed for structured practice after students have learned topics at school or with a teacher.
Yes. Skill Align uses subject-based access, so families can start with the year level and subject the student needs now.
