Public Health or Psych for UG Major

As of right now I am majoring in Psychology and attending class on campus at a State University, however I have the option of doing eLearning/Blackboard classes through University of South Florida for a BS in Public Health. I have taken Intro to Epi and Public Health Writing using USF's distance learning option and I would really like to apply for a Public Health graduate program after graduation.

I have a few questions I was hoping to have answered.

1) Would a Public Health undergrad major make me more competitive for a graduate program?

2) Given that most, if not all, of the courses can and will be taken through distance learning would that impact me negatively when applying for grad school?

3) I am currently getting some experience as a research assistant in the psych department (1 semester), but I'm a little confused as to how I would be able to get LoR's and research experience if I went the distance learning route at USF. Any ideas on that?

Any suggestions or answers that anyone can provide would be greatly appreciated.

Thanks,
Thales

Thanks for all of the responses!

I find that there are aspects of my psychology coursework which are very interesting (Abnormal psych, psychopathology, clinical methodology) but I definitely felt more excited about my time spent studying public health. Everyone has provided me with some sound advice which will help me make a good decision for my next semester.

If anyone has anything else to add please do.

Thanks!
