Hi all,

I am planning to give a major test shortly(in two weeks). What I would
like is to train my mind to have maximum attention and concentration
throughout 3-4 hours.

1) What preset would you suggest for this? The default BWGEN ones
would do the job? IN case you suggest custom presets, please do
elaborate a bit about how to create.

2) This test is going to be held at a specific time. Would it be more
preferable if I listen to that preset during that exact time for the
days before the test?

TIA.
