Transferring from a 4 year to a 2 year

I got accepted into a 4 year out of state private college and after some thought I had realized that this college wasn’t for me so I plan on transferring to a community college back home. Is it necessary to send the community college my transcript from my 4 year if i’ve only been here for one semester?

Yes. You will need to send that transcript. You also will need to send it if/when you apply for transfer to a different 4-year institution in the future. So focus on getting the best grades that you can for the remainder of this semester.
