Currently I'm doing Maths, Physics, Chemistry & Economics. I was considering dropping it after AS but after my Economics mock (did like half an essay and did not even complete the data response) i am thinking of dropping it and going with Maths, Physics & Chemistry for AS & A2, because i am not entirely ambitious about the subject, so i rarely ever find myself making any effort to further my knowledge & grades in the subjects. So would it be harmful to drop Economics, if i was considering Computer Science & Artificial Intelligence as my university course? Additionally i will be self teaching the C3,C4,FP1,FP2,D1 & maybe D2,S2 or M2 modules over the summer.
