advice for getting into cs

I got some of my grades back and average is not looking too good. I have something like 82-83 avg and next term I got dsc100, math 101, cpsc 121, astr 102. I was wondering to secure my chance in cs. what grade should I aim for this year and should I add or drop any of the courses, my cpsc grade going into the exam was like 92 and now it dropped down quite a bit because of something that happened during the exam, I talked with the faculty and science advising and I might be able to retake the exam next term because whatever happened was not my fault, I was lowkey hoping for cs to carry my grade. but yea... anyways I would jus like to assume the worst case that I cannot retake it next term and my avg this term stays like 82 percent... should I drop or add any courses. I got ab 83 in math 100 and honestly with a bit more effort I could've had ab 86 I believe. I dont know if I can get a high grade with math 101. Any suggestions guys please.
