If you apply to a four year college for the fall semester before are done with your spring classes at local community do they wait until send grades make decision?

Yes, most four-year colleges that require you to submit your final high school or community college transcripts will wait until those grades are available before making a final admission decision. They'll likely give you provisional acceptance or a place on a waiting list, pending the receipt of your final grades. The application deadlines usually occur before spring grades are available, but the final decision is contingent on those grades meeting the requirements of the college.
