Im currently in high school and applying to some UC schools to see what I can get into. If i decide to attend a community college, will my freshman grades impact my application?
The UC’s typically do not count freshman grades for first time (freshmen) applications unless it’s an advanced course (AP/IB/CC/etc).
High school grades have no bearing on transfer admissions at all and are solely based on collegiate level course work.
I just realized I misread your question:
For transfer applications, ALL college grades (which includes all community college grades) are reviewed for your admission.
I think you might be asking will applying as a freshman and then as a transfer create an issue. They do not look at freshmen applications when you reapply as a transfer. You’re fine.
