Hi. my gpa is lower than what i wanted but I am applying by June as an early admission. Is is possible that I take some summer courses summer of 2013 and then send in my grades to add to my gpa after i turn in my application in June 2013?
I could be wrong, but I think you only get one academic update and that window is pretty close to December 1st.
Depending on when your summer classes release grades, I would seriously consider holding my application to have those summer courses incorporated into my GPA. Alternatively, you can take your chances and include them when the academic update opens but that seems dumb because you'll also want to include your fall grades if the fall interviews don't fall through.
I sent in my application this past year in August after I had my summer class grades. My class ended late July though so I submitted early August. I was accepted so I think it worked just fine. I did feel like I was submitting kind of late for some of the schools I applied to that had earlier deadlines though.
