Definetly the alpha dose will help you remember and actually think about what your reading while ur reading it, so that you understand it alot better than if u were to just cram all that stuff. Alpha helps you to remember things alot better, like lets say you were in the alpha state while watching the matrix for the first time (a movie that is so complex that it usually requires that you see it more than once to understand the whole movie), you would be able to understand it in alot less time than normally.
And the day of the test, go ahead and use the beta dose, that will help u put words to paper fast.
