How to use GMAT QUANT REVIEW 2021 effectively?

Question

I recently bought GMAT Quantitative Review 2021. Before buying it, I completed all the OG questions. I am wondering whether the Quant Review is simply an extension of the OG, or is it for a different purpose such as offering questions for those aiming for a higher quant score. Can someone please explain how Quant Review could be useful in my preparation, and how can I best use it? I am already at Q47-48 level.

Thanks.

Thanks.

The OG for Quant Review is simply a quant focused extension of the OG. As such, it simply provides an opportunity for additional quant practice.

You could use it in either of two ways.

You could go through it and find questions by category and, thus, do topic-by-topic practice. For instance, if you wanted to work on Exponents questions, you would go through and answer each Exponents question you found, focusing on that one topic to develop skill in that topic. Then you would move on to the next topic and do the same thing.

Alternatively, you could just go through the questions in order doing mixed practice sets.

That said, if you are at 47 to 48 in quant, you still have some gaps in your quant knowledge and skills. So, you may want to brush up on some topics and find some other quant questions to do some topic-by-topic practice, and then use the questions in the OG for Quant Review to refine your skills through using official quant questions.

Thanks for your time, sir.

So, I am currently doing mixed sets and my accuracy rate has consistently been exactly 70% (Random mode; easy+medium+hard - all mixed up). I do understand that there are gaps in my knowledge. The question is how do I exactly figure out the topics that need some brushing up? Is there a sophisticated way of doing that?

Not really.

You just have to analyze your performance on the questions you have answered, considering, whether you knew how to answer them, how long you took, and your general comfort level with the topic.

Also, you could take a practice test and see which questions you took a long time to answer or didn't know how to answer.

One method I have used is to work on the types of questions I'd prefer not to see when I take the test.

Finally, you can find a list of all GMAT quant topics and check to see which you feel ready to handle and which you don't feel comfortable with.

Thanks. I think the best method is your method: doing questions I hate to see. I hate to see quadratics, sequences, and surprisingly, of late, divisibility problems as well.
