well- it's not fair to say, "avoided". but, usually the ones you got an offer for, but didn't get accepted after grades. If you didn't get an interview, applying again can be good- it shows you're committed to medicine and haven't given up.
If, say I hadn't have made the grades this year; my offer was AAB from all my med schools- if I had have reapplyed to them (you can only reapply under extenuating circumstances) then I would need AAA. You can apply to other universities if you have missed ur grades. Like, if I had no "reason" to have missed my grades, I would have reapplied to different unis for medicine.
Give them a ring; it can't hurt- but as far as I know, that's how it works.

Gud Luck!
