CAT 2020 slot 3 revealed how crazy this year's CAT has been. Like slots 1 and 2, the QA section of slot 3 was also dominated by Arithmetic. However, the emphasis on Algebra is slightly lower than in the first two slots. Similarly, there were not many questions from topics like Number systems and Modern Maths. There were 8 TITA Qs this year. Overall this section was at a medium level of difficulty. Selecting the right questions to attempt was the key. The best place to master the art of selecting the right question is CAT Question Paper. Practice questions with detailed video and text solutions from CAT 2020 Question paper to give your CAT Preparation the right direction.
