Dear Greg,
Although I watch classes regularly and have gone through the recorded skills improvement videos, I still feel that my skill level is deficient. Should I watch the lectures repeatedly for improvement or any other suggestions?
Hey Buddy,
this is not Greg impersonating! 
I am a fellow student and felt like replying, if you are still waiting for some response (and have not moved on).
I too had similar issue and here’s what I think will work. Since regular classes and listed videos are mixed (due to various reasons), suggestion would be, start with the 1-month plan and if you still have good time left after completing it and before you admissions schedule and such, consider doing to 2-month plan. Those are little structured and starts easy to difficult.
