What other topics & books should I encompass in my studies?

I am looking to relocate to the Panama City Beach area and am studying to obtain my FL real estate license.   

Later on found BP and have been studying ever since.

Lots of agents also spend a good bit of their time continually learning, studying properties on the market, taking classes to perfect their understanding of new laws (hello, smoke alarms in Maryland!!)

According to a study I saw, when everything thing is said and done, Opendoor makes about $7,000 per house.

I am a junior in college studying construction management.

Study some, but don't wait until you are completely comfortable to jump in. 

So, I'm new to the game, and I don't really know what I should be doing when it comes to actually executing the BRRRR method, its one thing to know it and study it, but another to actually do it.

I do agree with @Anthony R. that you need to be sure to include enough in your budget for repairs and also Capital Expenditures (new roof, furnace, etc) I think @Ben Leybovich did a study a while back and found the average home in American needed about $250 in repairs per month if you really figure in everything that will eventually wear out (the entire home accept the foundation and framing).

Since I have been studying here and listening to financial independent discussion, I often hear that their service can help you achieve the goal you set.
