# Core 4 Study — C4.12 student guide

The website includes the latest Monday–Friday C4.12 lessons: twenty-one numbered questions per day and separate extra conversion practice. Topics cover fractions and ratios, decimals and percentages, money and finance, and patterns and algebra.

## Practise with understanding

Try the question before opening support. A conceptual hint gives a starting point. A worked example uses the same type of method but different numbers. Reveal its steps one at a time, then apply that method to your own question. The example's answer is not your answer. The website does not reveal the actual question's answer or working.

## Answer checking

Enter your own answer and press Check. Follow the required answer form, including simplest fractions and compact/index notation when asked. Type a/b for a fraction, use a space in a mixed number, and use a caret for powers. Put repeating decimal digits in parentheses to give an exact recurring value.

Question 10 provides three percentages: fill in their decimals and simplest fractions. The extra conversion practice is separate from the original numbered questions.
