I was accepted to Brooklyn College for the spring 2014 semester as a transfer student but was not able to attend. I reprocessed my application for the fall 2015 and was admitted again. However, they have not seen my fall 2014 semester grades from my last school since when I originally applied the semester was not finished. I want transfer credits for some of the classes I took but I failed one class. If I send them this updated transcript for the credits could they change their decision to enroll me because of the failed class even though they already accepted me?
Yes they can. If you want to attend Brooklyn they will eventually find out about the grade because the transcript must be sent. You might as well talk to them now and see what can be done.
