I happen to be at the same time as you. If it is a school-wide elective course, it needs 10 credit, which is only required for students of grade 08. If it is a large class of elective courses such as mathematical modeling, English (second semester of sophomore year) and Matlab. It takes six credits, but this is only part of the college. If you want to know other details, you can consult your peers. They will have your college's training plan, which lists in detail the credits needed in different aspects ~ ~ ~ PS: 8 extra-curricular practice credits, computer level 2, 6, summer practice, driver's license, coach's license and subject competition.
