I failed to pass in the small amount of maths which are still required for the course.

This should be 'which is still required'.

This is because 'amount' is the subject of this verb.

The 'small amount' is a singular concept, even though 'maths' seems like a plural.

That is – 'A small amount is required'.

[Interesting that the term 'math' is used in the USA]

Relax and pass those tests!
