MS in Finance or Trainee Program?

Hello all,

I am a junior undergrad student. I recently decided I want to pursue a career in finance. I am not saying I am an expert, I just love studying and learning about it. It is definitely what I want to do as a career.

Currently, I am trying to decide if I want to purse an MS in Finance after undergrad or do a financial advisor trainee program. I want to learn more but I don't want to pay graduate tuition. I recently learned about ML's PMD program and have heard both positive and negative feedback. I also know firms like Morgan Stanley, Ameriprise, Wells Fargo and Edward Jones offer similar programs. I hear they are intense but I couldn't care less. Effort and long hours don't bother me. I just want to be 100% sure I wouldn't do a trainee program and then not complete it. I also want to be sure that the program would ensure my foundation in the financial sector.

I genuinely want a career in finance; just not sure which is the better and/or safer path. Any insight is tremendously appreciated.
