For any psychiatrists plz help me!!?

i want to become a psychiatrist im in a junior college right now and plan to transfer to uc irvine or ucsb next fall. i am wondering if you need calculus 2 in the long run to get into med school. i took calc 1 and got a C. my overall gpa for my 2 years at the junior college is a 3.75. i still have one more year to go. please advise me because calculus is not my strong point at all. thank you in advance for your help :)
