Best Test to increase your Score

I purchased the Gmat Club Test and found it really helpful.test mode - even though some of these questions are available else where, it's hard to click each link and read questions and answer. these tests provide the questions in a testing situation. lots of practice in quant- most are difficult questions. My weakest math is algebra (I usually plug in numbers), a lot of these questions are high yield (algebra and inequalities) where plugging in numbers won't work Review each and every question and make your own quizzes for the weak areas.After the end of 1500 questions I felt much more confident in Quant . There was a lot of improvement in DS , my weak area as the test covered each and every type of questions .The questions are close in what the actual GMAT asks .It was surely worth every penny spent. Verbal is poor question quality explanations for both QV are shoddy at best. I don't mind the extra practice questions,
