I am not sure I understand why all of your credits from the semester will be gone? Is it an option to stay at your current school? Are you taking classes second semester?
The National Student Clearinghouse has a record of all transcripts from all colleges that a student has attended, so yes, schools will find out you have attended college…so don’t be dishonest when applying elsewhere.
Because you have completed a semester of college, you will be considered a transfer student at most schools, and will have to report your grades and transcript from the college you are currently at.
There are some schools that may consider you as a freshman, depending on your specific situation…you will have to do some research on that. Community college would certainly be one option, as would other open enrollment universities.
