Will it look bad if I retake courses? In terms of Top 5 college admissions

I am guessing something was edited out of your original post, but if you are transferring from CC to a four year college, I believe the original course still appears on your transcript. This may not be true of all colleges. If you took Eng 101, got a C, retook it and got an A, it will show you took Eng 101 twice, but the most recent grade will be used for your GPA.

Be aware that it’s even harder to get into those schools as a transfer. 1, there are very few spots. 2, the standards are perhaps even higher, because they still want to see how you are involved with life outside of school. 3, as a transfer, you need a very solid reason why that college is the one that can meet your needs as a transfer. Your essay will have to be totally spot on.

Have a look at this:
In 2019, Harvard University received 1548 transfer applicants.
The school accepted 15 students. Therefore, the transfer acceptance rate for Harvard University is 0.97%.

How many of those students had C’s? I don’t know, but I’m guessing it was very few.

Who is going to pay for you to retake those classes?

The fact that you merely state Top 5, rather than a few select colleges that might have the best offerings in your major, is a red flag. You can be very successful and not go to a Top 5 university, or even a Top 100 university. In your shoes, I would try to figure out how to make the most of what your realistic options might be.

@whydoidothis , just saw your post.

Still, the general gist is the same. Apply based on your actual grades and scores, not what you hope they might be if you retake. And yes, colleges will see the original courses. They will reject kids with perfect grades. Retaking those classes is not going to help you.
