I have some major red flags

[child of 2]

When I was in high school, I took some college courses, and did terribly. Junior year, I took calc III and got a B+. That wasn't so bad. My senior year, I took diff eq, theoretical linear algebra, and a com sci course (my first programming class) and got D-, D+ and F, respectively. Needless to say, I got rejected by all the schools I wanted to go to, and ended up at the local college. I retook those classes so that my GPA isn't in the toilet. But the D-, D+ and F are still there. I went through a terrible period of depression my junior and senior year. I had no real friends, and my parents hammered me with dissatisfaction and verbal abuse everyday. It still p*sses me off just to think about it.

How will this impact my chances of getting into good grad schools?

I did go through depression in college, but that was when I still lived with my parents. Now that I moved out, I can finally put my past behind me. the thing is, this is kind of personal, and I don't really want to have to explain it in my application.

What can I do?

I had a similar rough patch at the beginning of my undergrad career. I made up for it with high grades latter, and a 4.0 in my MA (so far). Contrary to popular wisdom, I made no mention of the lower grades in either my MA or Ph.D. applications. So far as I can tell, the turbulent beginning has not hurt my chances anywhere. My experiences are but my own, however, and might not be of much help. That said, I would not be too despondent about the situation. If you work hard going forward, no doubt you will gain admission to the field of your choice.

I know the feeling. But if you do well your last two years, they will look at the improvement and where you ended up, rather then where you started out. While you did not do great, at least you can make an agrument for at least trying college classes in high school, which is better then those who never did.

So what I would say is this, try to build up other experiences (research, teaching/tutoring, etc) and continue to improve your grades. If you do that, then there is no reason why you can make an agument for your ability to be a good grad student.
