Hello friends!
I am also using this app. And I was starting by solving some questions from the chapters. Testbook questions were very easy and few are of moderate level. I obtained 150+ in Quant and English both. And it takes time to load the questions.Most of the questions are irrelevant and also most of the questions are wrong. The app doesn’t contains the information of the content in depth and are not also described .
Very easy Question are there compared to other sites.The service support is very poor because when I report some questions they doesn’t answered me. They also doesn’t rply to your mail.
And you can’t change your score from the test.I would recommend you to go to oliveboard app.In this app you can face the same difficulty level as in you are doing in exam. Hope you find it relevant.
Thank you.
