Hey Lost...Don't worry, Just wait for your interview to come. I am in your position as well, however i am finishing the requirement in April06 and seeking admission in Sept. 06. Finishing in Aug and starting in Sept. may be a long shot but you should also speak with admissions about that. I know that for Sept, they require my tuition by Jul 15th...Plus, counting other factors such as loan (application,processing etc. etc)...I wanted to give myself 4 months to wrap up all the stuff @ home here before I depart for the good coming 28 months in Sept. So just do your calculations (about time) and see if it suits else they may automatically put you or recommend you Jan 07 in that case.
Also, mine is a provisional acceptance upon completion of pending courses successfully...So I would assume yours to be the same scenario should everything go ok. Gpa wise, If you are motivated and show steady improvement, that'll help. Mine isnt the greatest @ the moment, I am at 2.7 but hope to finish with 2.8 atleast by the end of april 06...
Do note that to progress from Premed to Med, you require a minimum 3.0 but I do understand that some people who started in premed and now in med were able to maintain 4.0 throughout with determination.

Good luck and stay positive!!!
