Sbpa0, If your school starts on August 16 or earlier then you are fine. Because that gives u the 60 days grace period but if it doesn't then you may have to go back home, wait until September end and then come back to work with H-1b stampped in Kathmandu. I had the same situation but what I did was I enrolled for the late summer session(the school had two sessions). So, by the time the summer session was ended, I had 60 days till October. It would have been nice to elaborate if you had given us the exact date of your class startig for Fall session. BUT, in my opinion, if it's a week or two here and there, you should be ok. Again this is all my opnion. Please do more re-search.
