how to pace yourself on sat to get 1550+

hi guys i'm consistently getting around a 1500 on sat practice tests. i always struggle w a few hard reading comprehension/ vocab questions in RW 2 and the hard questions at the end of math module 2. what do y'all recommend to improve my score from where I am now for the march sat and how do you think i should best split up my time on the test or any test taking strategies you may have. thanks!
