Finishing required transfer courses in Spring and Summer

If I take two required math courses for 2019 transfer in Spring and Summer, instead of Winter and Spring, will the UCs more-or-less automatically reject my application?

I expect so, but I wanted to double-check since I dislike my current math teacher for Winter session.

If it says the courses are required (not highly recommended) taking one in summer will almost certainly cause a rejection. Additionally, if it’s recommended but in a highly selective major, it could have an impact.

Thanks.
