GATExcel 80

There will be 80 tests which will cover the entire syllabus. The tests will be useful for you to evaluate your preparation. It will help you if you first watch a topic's video and then take the test related to that topic. At the end of your preparation, you can take the full length tests. Each test will be released at 6:00 PM (IST) on the day it is scheduled. Once a test is released, you can take any time before 5:59 PM, 31 March 2021 (IST). Once a test is released, you can take it any time before March 31, 2021. You will be allowed to take a test only one time. For every test, you will immediately see your result as well as the explanation. We will occasionally add more tests whenever we feel the necessity. Please find the detailed schedule below.
