Is that overloading? I've just recently purchased them all and was wondering if it's ok to begin them all together or should I work through them one at a time, and if so, which one should I begin with?

Use Personal Genius (I think that is what you mean by GC) in the mornings before school or work. Use Memory Supercharger evenings after studying or end of the day to remember the important stuff from the day.

Some time ago I used three paraliminals a day. I worked okay for me.
