You know the drill, GCSE Higher students, practice makes perfect, right?! Well, it certainly helps a huge amount and these manipulating and simplifying algebraic expressions questions are a great way to prepare for exams.

GCSE Maths courses place a heavy emphasis on algebra. Like it or not, the topic consumes a mammoth 30% of the mark on higher-level papers and you’ll do yourself a huge favour by practising how to manipulate and simplify algebraic expressions effectively.

So, where to start?

Diagnose your stronger areas and your areas in need of improvement with suitable practice questions like those in the quiz below. Use the questions below to find gaps in your knowledge. The quiz will tell you exactly what you need to cover in your revision from this list of topics:

– Index Laws (Algebraic)
– Changing the Subject of a Formula
– Forming Expressions
– Simplifying Algebraic Fractions
– Adding and Subtracting Fractions
– Multiplying and Dividing Fractions
– Algebraic Proof
