Hi all! I'm new to this forum so apologies if I'm asking an easy question or one that pops up often in this feed. Please redirect me if that is the case. I am currently a junior, Actuarial Science major with a Comp. Sci Minor at a relatively small, private Midwestern school (North Central College in IL for those who may have heard of it). I went through my Undergrad not really knowing what I wanted to do and did not really make the most of my schooling. I'm going to be a Senior next year and have taken all of the Calculus sequence, Java, Databases (SQL and the sort), Probability/Statistics and a ton of Econ, Finance and some Accounting Classes here and there. Unfortunately, due to a hospitalization the Winter Trimester of this past junior year, my GPA has plummeted to a 3.529 (cumulative)/3.665 (major) since I was forced to make up all of the work by teaching myself my courses and turning in the work once I returned. Unfortunately, one of those courses was Probability and Statistics which I received a C in, since I had to miss most of the work required of the class. I was originally thinking of just applying to Actuarial roles for once I graduated but after second thought I have really liked the idea of applying to do either a master's or PhD program for Biostatistics (preferably at a school like UChicago since it's close to home). With no real research/relevant experience and my poor GPA (and statistics grade) I'm worried that I am not at all competitive. I have not yet taken the GRE so I plan to study hard for that. I do have an internship with a large Healthcare Insurance Firm in Chicago this summer and have already taken and passed 2 actuarial exams (in financial mathematics and probability, ironic enough). Which classes should I be looking into next year to look more competitive during application season? Is there anything I could work on to improve my application in such short time? Which schools do you think I should apply to or would have a good shot at? Thanks so much and sorry for this wall of text!
