Simultaneous equations require students to find values that satisfy two equations at the same time. Foundation students solve linear pairs, while higher-tier students tackle one linear and one quadratic equation together.
Our tutors see these errors again and again. Knowing them in advance gives you a head start.
Subtracting when the signs are different (should add) or adding when the signs are the same (should subtract)
Forgetting to find both variables after eliminating one
Substituting back into the wrong equation and not checking the answer
This topic is tested by the following exam boards. Our tutors are specialists in each one.
Linear equations are one of the most frequently tested algebra topics at GCSE level. Students must isolate the unknown variable by applying inverse operations, handling brackets and fractions along the way.
AlgebraQuadratic equations appear throughout the higher tier GCSE paper and are a significant step up from linear equations. Students need to factorise, complete the square, and use the quadratic formula to find solutions.
AlgebraStraight-line graphs are tested at every tier and form the basis for understanding gradients, intercepts and real-world modelling. Students need to plot lines from equations, find gradients and interpret y = mx + c.
