I like sports and swimming is my favorite. Doing physical exercises keeps one fit and healthy and helps one work more efficiently. I think we all need to strike a balance between work and relaxation. This can keep us energetic and help us do our job better.
However I wasn't very good at the sciences or didn't have a lot of help in the sciences or something but certainly didn't set science for my A level. And when I came to take my A levels I didn't get a good enough result to go to University.
