Where do I start?

Hi, thank you for taking the time to read this. Prior to going into college, I was an exceptional student—20+ AP classes, very high SAT/ACT scores, etc. I majored in management at a non-target university (with no intent of ever working in finance) and unfortunately had a series of personal trials and tribulations that resulted in my college academics being completely unremarkable. Anyways, it has been two years since I graduated and I have realized I want to be in a finance role (ideally VC or PE).

I have decided to go for a Master in Finance (ALM) through Harvard Extension School. I know it isn’t viewed as being as prestigious as the business school. Also, I have taken and passed SIE, Series 63, Series 65 and began studying for my CFA. I would like to have at least two of the three levels done by the time I graduate. I am also taking the Wall Street Prep certifications in Financial Modeling & Valuation and Sell-Side Equity Research. Will I stand any chance of getting into a good firm if I have a 3.75+ GPA? Basically, I feel like I’ve wasted several years of my life and I am desperately trying to get back on track while I am still young (24). I just feel like I’m stuck and don’t know what I should be doing. I would appreciate any advice. I did not have undergraduate internships in finance because, I had no interest in finance at all.
