PSAT Critical Reading Section Problems. Help Please!?

<p>My CR score ranges from 49-57, and that's really lowering my overall PSAT Score. I'm aiming to get at least 210, but the CR section is really making it impossible. I've tried applying some tricks I've been taught to get higher scores, such as:
Not looking at answer choices first
Making notations around the passages
Predicting the answers before actually looking at the answer choices,
but it just seems to never work. It may be that I don't know how to apply them, but I'm pretty sure, there's more to what I should do, as for getting a higher score. Can someone please give me some useful tips that they found helpful when taking the PSAT? (Trying to get at least 620 or higher, and I only have 8 days before the test date arrives)</p>
