I started the 2-month plan(specifically the integers and Primes, and Factors and Multiples), and when I tried solving some of the Quant progress Quizzes specifically the Arithmetic Progression Quiz #1 & #2 my results were extremely poor for all. However, I was advised that before I move on to another topic, I should make sure I get very good results at the one I’m working on to reflect that I fully understand it. So I want to ask what is the best way forward? Do you advise I keep solving questions or I change the plan?
