mtt study

What is the best way to study MTTs at the moment I'm doing run it once from the ground up MTT course i have an octopi personal subscription and do work within solvers on there but how should i be using the solver, are there any specific drills i can be doing. How much studying/playing should i be doing id like to say I'm at the top of beginner or low intermediate stage. I have poker tracker 4 and review hands after sessions i have a lot of free time so tend to play and study 5 days a week. Any tips on solver work or study schedules and courses that have improved others would be appreciated.
