There's obviously a ton of content review out there for these subjects. Nonetheless, I find that a lot of books advocate different reading strategies for these sections. Some say to read the passage and then do the questions one by one, all in a row. Other texts say to initially skip the passage, skim over the questions, and then read. What has worked for you all? Personally, I've found that I've undervalued the value of the passage paragraphs in the past. Even if I get a passage whose content I know particularly well, the passage might sneak in one or two critical words that you NEED to answer the questions. So, this has me thinking that the best strategy is to speed-read the passage thoroughly, and then answer the questions based on difficulty (easiest ones first, hardest last). PS: let's keep this to the science sections, since there are already 10+ guides to verbal.
