How to get a grade c in GCSE maths

Updated on June 21, 2012

c grade gcse maths

I will show you how to get a grade C in GCSE maths. I am a private tutor who has helped hundreds of students to up their grades. Many students have moved from an E to a C in ten lessons. Some of my students have letters from the exam board informing them that they achieved full marks in their exams. Many of my pupils have also moved from C grades to A and A*. But in this hub I want to concentrate on getting the magical C grade.

I am in the process of writing a revision book for GCSE students which will be free because I want young people to succeed. It will be published through smashwords, a free publishing service and will be available at online publishers.

OK, you need to master algebra, formulae, Pythagoras and percentages to get started. The good news is that they are heavily connected and learning some simple stuff will get you scoring far higher marks than you have ever got.

Let's start.

6 + 4 = 10

6 = 10 -4

The rule is that when something is adding or subtracting, that it changes its sign when it jumps over the = sign.

8+ 2 = 10

8 = 10 -2

That 's true. Isn't it?

8 -2 = 6

becomes 8 = 6 + 2

So x - 4 = 10 becomes x = 10+4


x+3 = 10 becomes x=10-3


To get a C grade at GCSE you must know how to manipulate 3 x 2 = 6

3= 6/2


When multipliers jump over an equal sign (=) they become a divider,

All you have to do is really understand fractions and you can get a C grade or even tackle A grade questions.

3 x 2 = 6

3 = 6/2

So 3x = 6

becomes x= 6/3 ( 3x means 3 times x )

so x =2

Now try this.

3x - 4 = 8

3x = 8 + 4

3x =12

3x =12 ( this means 3 multiplied by x) So the 3 becomes a divider if it jumps over the + sign.

x = 12/3


Try this one:

(2x+2)/6 = 2

Dividers become multipliers

2x +2 = 6x 2

so 2x +2 = 12

2x = 12 - 2

2x = 10

x = 10/2

x = 5

I show my learners this connection. These simple rules apply to algebra, formulae, pythagorus, trigonometry and even percentages.

2/3 = 4/6 is the basis for many A and A* questions.

There are some easy questions on the higher papers that are based on this.

So try these questions. Find the value of x.

1.) 5x = 20

x =

2.)4x + 3 =11

3.) 4x +3 = 23

4.) 5x -10 = 5

5.) 3x/10 =3


1.) 5x =20

x = 20/5

x= 4

2.) 4x + 3 = 11

4x = 11 - 3

4x = 8

x = 8/ 4

x = 2

3.) 4x+3 = 23

4x=23 - 3

4x = 20

x = 20/4

x =5

4.) 5x - 10 = 5

5x = 5 + 10

5x =15

x = 15/5

x = 3

5.) 3x/10 = 3

3x = 30

x = 30/3

x = 10

      Anyone can get a grade 'C' in Maths GCSE ...we had a wonderful maths tutor, Dr G. C. [sadly retired] and he was so patient and calm.

      He taught at colleges and said so many adult returners to education had been terrified by maths in the 'O' level days, and harsh teaching methods, and fear of the subject and fear of 'ridicule' was what was holding a lot of students back.

      A fresh approach, a good teacher, and a grade 'C' is within anyone's grasp..

      I met a young man who was studying engineering at a London university and he was passionate about teaching maths- like Dr C he said that clear explanations and making it interesting and understandable for people was the key.

      Hi, I am due to sit maths gcse in June this year and really need a grade C. I'm sitting the higher paper with edexcel.

      Any tips would be appreciated as your blog on achieving a grade C was very interesting.

      Thank you look forward to hearing from you.

      Im going to say yes cause even if other ppl did, Im sure mines the best. :)

      Hi Beth. It is the minimum grade you need to get in maths to get into university regardless of what subject you are to study. Around 50 percent of students get a C or above. Some students are still trying to get this grade at 17/18 years of age. most get it at age 15/16. Hope your hubbing is going well. Was it you that wrote a really good hub about a stuffing recipe?

      Is a C a good grade where you live?

      I wish there were far more hubs on educational subjects! This is a rarity! Cheers!

      As a small "ps" - if you had a couple of pictures and put them in here, with the numbers and fractions printed on them, you'd get more reads and comments, perhaps!

      Cheers! Thanks for following me too!

      Thanks for your kind comments. The great thing about maths is that students can go from low scores to really high scores in a short period of time.

      Wow, I wish someone had explained that to me when I was trying to learn algebra. That would have made things so much easier! Thank you for sharing this! Voted up, useful and thanks for SHARING.
