Will memorizing prefixes and suffices help me get a better CR score?

Hi everyone! I wanted to ask if I should spend time memorizing prefixes and suffices to increase my reading score. Basically vocabulary is the only reason why my CR score is pretty low and I wanted to know if memorizing prefixes and suffices will help. If you think I should, can you please tell me where I can find the best ones to memorize. Thanks!

You can find a list of prefixes/suffixes here:

If you are decently fluent at English, you should be able to recognize most or all of them. But keep in mind the meanings of many vocab words can’t easily be determined from this list alone.

Probably no. The vocabulary is a really small portion of the grade. That would be more or less useless. Find some tips on how to solve vocab questions. You don’t have to know the definition of a word to get the question right.
