>>11900764for memory what I do is after a study session I go review and pretend as though I am teaching someone else in the most basic way what I just learned
for conerntration I try and remove all distractions as well praticing self discipline in that I just have to finish this,
It also helps I guess to reward yourself I think, ie I treat myself a nice meal so long as I am able to maintain my concentration during a session.
breaks are also important, the longer a session was the longer a break should be as well to allow yourself to process everything
