improving SAT reading comp score

<p>hi So I always get a 550 on my reading comprehension section of my practice SAT tests. I really want to improve to a 700+
everyone always tells me that I should read more books & newspapers. they say that will definitely improve my reading skills. I try to do that but I just don't understand a lot of what I read. I could look up vocab words but that still doesn't help me fully understand what I read.
I just don't get how reading more and more can improve my scores if I can't understand what I read. can anyone help me? :(</p>
