Hi AkiB,

When are you planning to take your Official GMAT? Since you're using the 60-Day guide, you've got 7 more weeks of assignments to work on, so the amount of time between when you complete that plan and when you take the GMAT will impact the materials that you COULD use.

Hi AkiB,

First of all, thanks for your kind words about the Study Guide.

For many students, the OG13 will provide enough practice to prepare for the GMAT. Others may need/want additional practice, especially if they have a very high target score.

Let your practice test results guide you. Once you've covered all of the content, you'll begin taking frequent practice tests. If you're scoring close to your target score, then the OG13 will suffice. Otherwise, you may want to get the official review book for quants.

If, after you've answered questions from the official guides, you need/want more practice, you can find thousands of questions on this very website. You can also use BTG's tagging feature to isolate one concept. For example, here are all of the questions tagged as statistics questions: https://www.beatthegmat.com/forums/tags/ ... statistics
See the left side of that linked page for more tag options.

I hope that helps.

Cheers,
Brent
