Has anyone successfully transferred to a 2 to 4 university with one or two more (W)?
Yes. Lots of people do.
Thenk you, I was so worried that it will affect my chances on getting accepted. When doing the application, do I have to explain why I withdraw the course or nothing?
Some applications will have a place to discuss things like that, but many won’t.
Lots of students have to drop classes for all kinds of reasons, so it really is pretty common to have at least one W on a transcript.
Thank you! I can finally relax, and not withdraw again 
I have two, but it’s for reasons.
