Missing maths!

I studied excel A level maths and Loved it but ultimately deceided to go into biology instead. I really enjoy the challange in maths questions then the satisfaction in getting the right answer. Having just finished year 1 I'm very happy with the degree I chose but I miss doing maths- any suggestions for maths I can do or learn for fun going off of A- Level maths- especially during the summer.

Look into Further Maths. If A Level Maths was a jump from GCSE, FM will be another jump up.
FM would cover content some of the content that you would have covered in the first year of a maths degree.
If you want a link on how to study maths from scratch up to graduate level in private, let me know.

Thanks for the reply! This is actually the main conclusion i reached when talking to a friend about it so i'm borrowing her further maths book and going from there (:
