Hi every1 at SMU, i have been reading all the posts on this forum and have been learnin lots as i am in the process of lookin for a med school that suites me right.....so i just got the broucher and will be workin on it the next couple of months so i will be lookin for help along the way....but first an for most i have a quick prereq. question. I am a 4th year BioSci student and will be graduatin this year but i am lackin Physics so what i have done is registrared for it for the next semester, now if i apply and hand my application w/out a grade for physics can i get conditional acceptance and when i am done will they take me...... also how many students are taken for each class, and when is the best time to apply (therefore least number of applicants)

Thanks! Lookin forward to learnin lots from u guys and any help would be greatly helpful...
