Hi Yogi,
I agree with VYC and None. I had straight B/B-'s one quarter after getting pneumonia, and I've even had a couple of C's in my college career.
When I was applying, I was advised not to put this in my personal statement b/c it's negative, and b/c more important, positive, personally significant experiences should go there.
Also, one of my professors who wrote me a letter of rec actually offered to explain my illness and other academic difficulties in his letter (albeit, briefly!)
Despite these blemishes in my record I ended up with 8 interviews, and one acceptance. I had the opportunity to explain all the blemishes in my record at pretty much all of my interviews.
So I think for now, emphasize all the wonderful things in your record where it counts--in the personal statement and the AMCAS. Aim for getting interviews. You can explain everything else when you interview, or perhaps those who write your letters can throw in a line or two on your behalf.
Best of luck!
