so i have finished my 3rd year of Mpharm at university of Bath and i like the course and i am willing to finish the degree but i have become interested in engineering (particularly chemical engineering). i am not the best person at maths, i did not do maths or physics at a levels so what are the opinions of me doing a level maths at 23 and then applying to engineering??? please please please let me know if this is realistic or not.
