Pupils across Kent headed into school this morning to pick up their GCSE results.

Despite exams being made tougher, the number of students getting top grades has risen for the second consecutive year.

But for those who haven't been in the classroom for a while, how well would you do in these tests?

Provided by mock exam company Exam Paper Plus, the five questions below should be of similar difficulty to a maths GCSE paper.

As a rough guide, if you get all five correct, you would likely be a grade 9/8/7 student - or A*/A in old terms.

For a 6/5 or B/C, you will need four right answers.

Three will get you a 4/3 or C/D, and two will bag you a 2/1 or D/E.

If you get less than two, fractions and algebra probably aren't your strong point.

The answers are below so don't scroll until you've finished.

So, let's find out whether you'd be a star pupil:

1) x = 3.5

2) 3 walls

3) 0

4) 27, -3, -5, 3

5) 19 bags
