@52471699386435 I too have been struggling in mocks to let you know you're not alone.
What I've been trying to do is to set an internal timer. While I don't look at it after every question, I do look at it as follows -
* First 5 questions done - 35 minutes left
* 10 questions done - 25 minutes left
* 15 questions done - 15 minutes left
If you forget key concepts or go blank, you need to take the best guess and move forward. I also face a similar issue.
A good advice would be to use flashcards to help you remember key concepts. GMAT club has few of them and a lot of flashcards are otherwise available to help you quickly go through key concepts before any tests.
I am now planning to use flashcards. Although I feel going through them just before exams helps. Once I see the solution where I struggled solving, the concepts seems something I should be knowing and should have mastered 😂. Thanks will try this
