And no... you will likely not be allowed to drink water during the test... the only time you can drink something is during your break... load up on fluids and use the rest room before the test starts so that you can last till the break...
Exactly what @blah170blah said... Finish the coursework, drill and BR before touching the rest of your PTs. Also, focus on LGs because that section actually helps your score.
