I am taking teas v next month n have been studying since past month. So far I have reviewed the teas practice book. Does anybody know how deep I should review the science part or it's ok to have the level of knowledge that the bk has covered. Sometime I refer to my old science bks , but end up feeling I wasted too much time reading too much details. Will I be safe jus to keep myself limited to the level that they follow in the bk for science part
