Let's say I have a blemish on my college record--for instance the fact that I took medical withdrawals my first semester and started fresh a year later at a new school. At my current school (a tier 1 research university), I have done extremely well and am planning to complete an honor's thesis this summer. My lab advisor (someone who picks her own graduate students) said she believes I have a very strong application, but she doesn't know about that first semester, and I'm concerned it will reflect poorly on me. I can very clearly explain why those withdrawals happened, and I think the reasons are good.
Do I need to send graduate schools the transcripts from my first school?
Should I attempt to explain the circumstances around those withdrawals in my SOP, a separate letter, or only explain if asked?
Thanks!
