I was a business student for my first two years of undergrad but then switched to computer science. I took classes over the summer before my junior year at another school. During my junior year (which I am in now) I am/have taken 7 CS/upper level math courses. During the summer I am doing research and taking non-cs/(core classes for my undergrad curriculum) so that I can take only CS classes senior year. Fall semester of senior year I plan on doing an undergraduate thesis class and take two grad classes, along with another course.

How bad is it for my application if I only have my junior year and first semester of senior year for the admissions committee to review.

I have pretty good grades in my cs/math classes post sophomore year (A's/A-). I plan on having two good recs at least. My main concern is the lack of semesters for the admissions committee to judge me on.

The first two years of undergrad in the US are mostly general education classes anyway, so I wouldn't worry about it. It is common to switch majors.

You seem like you are in great standings. You've taken a fair number of CS classes, received good grades, and will have two good letters. On top of that you'll have research experience and plan to take a few graduate courses.

From the little info you've provided, you seem like you are well on track!


People have gotten into CS graduate programs (including PhD programs) from separate fields before (such as math/statistics, etc.) so it is definitely still possible in your situation; although since you switched to CS junior year it may take a little longer for graduation, but it depends on how far you are along the required coursework at your school.

If you are worried about this, you should be able to explain it in your statement of purpose, and keep in mind several people are in similar situations (switched fields, maybe had a not so great first couple of years).

To start, I would definitely recommend that you continue doing research if you are dead set on getting a PhD, especially since that is the best source to get you good recommendations that you will need for grad applications. I'd also start figuring out what your interests are in, and take electives/grad classes based on those to help develop those interests so that you will have an idea of what programs/areas you may want to work in and how to articulate that in the statement of purpose.
