Hi,
I hope that you are well. Here are a few suggestions:
1. Practice your reading. I've posted about this before but the idea is that you should be reading GMAT-Like articles every day to improve your reading speed and comprehension. I like the economist. When you do this reading take your time and try for FULL COMPREHENSION. Re-read sentences that you do not understand and read with a dictionary so that you can look up words that you do not know. As you read think about the main idea of the passage and how the author supports the main idea. Also think about what assumptions the author might be making.
2. Practice with an
error log. Keep track of every question that you got wrong or had difficulty with so that you can analyze the question types that are difficult for you. Then you can focus studying content to reinforce your weak areas. Also, periodically re-solve the questions in your
error log and remove the questions that you have mastered.
3. Try to stick with real GMAT questions. There are good "fake" math questions out there BUT I am skeptical about the quality of "fake" verbal questions (I have sampled verbal from a bunch of different sources and I'm just not a big fan of anyone's questions.) Verbal clones are much harder to create. That said there is enough official stuff (especially easy/medium questions): You have
the Official Guide, The Verbal Review, The 9 GMAT Paper Tests, the 10 FLTs, Question Pack 1, GMATprep (and prep docs), and if you are desperate for more practice there are TONS of LSAT critical reasoning questions and TONS of GRE/LSAT reading comprehension. You can also use SAT sentence correction which is far easier than GMAT but OK for basic practice. You will lack CAT verbal (besides GMATPrep) but the paper tests can give you a pretty good idea of where you are scoring.
Happy Studies!
