Truth is study what works for you. Realise that other actors study, show up prepared and on time for all classes, work outside of class with their scene partners, and are trained in many "methods" and skills.
FYI: for true method training you need dedicated actors, a coach who is also able the you back down (or up) from emotional highs and lows and closed environment where people you do not work with have access and a willingness to put you sould out there to see
Do what is best for you.
