Withdrawals don't look great, but I would think they would probably make or break you based on your provided reasoning during an interview rather than stopping them from giving you one.
If there's one thing I can tell you, it's to dominate the MCAT. A highly competitive (above average matriculation) MCAT demonstrates the ability to do a couple things.
1 - Understand complicated material and apply it.
2 - Study and, most importantly, perform adequately in an anxiety-inducing situation in a way that surpasses your peers.
Your overall GPA isn't great, but recently it seems very competitive. An increasing GPA, especially in the last couple years, and a solid MCAT shows dedication after realizing your dream, and an ability to perform to acceptable standards academically.
There are early problems with withdrawals, but if it means anything, they afforded me a chance to explain an abysmal sophomore year GPA that included both semesters of inorganic chem, bio and physics. My GPA after that year was impeccable, and my MCAT scores good, and they told me as much in the interview.
Some specific questions they asked me that you should probably prepare responses for...
-What the heck happened here? (no lie...it's how they asked)
-So what changed from that point to no? Why did you perform better later, and what will stop you from stumbling like that again?
-What will you do if your grades begin to suffer like that again? Do you have a plan to nip it in the bud? (They may not ask you this, they were asking me in regards to a serious illness that has a tendency to rear it's head viciously for weeks at a time)
Community College classes don't look that great either, so it would definitely be better if your better GPA was from a 4 year university.
The short and skinny of it is, do well on the MCAT and have a solid answer for those questions. I can't imagine you won't be interviewed anywhere if you apply broadly.
Good Luck!
