About The Course

Course Description

The quantitative section is an essential part of most competitive exams. A lot of times, calculators are not permitted during them and even if they are permitted, a lot of time is wasted while typing the numbers on them. This course teaches you techniques by which, just by observing the question, you will be able to find the right answer. It can help you utilize that time for further questions since we have limited time during the exams.

It has 61+ lectures spanning 8+ hours of on-demand videos that are divided into 18 sections. Each topic is explained extensively - by solving multiple questions along with the student during the lectures. The students are also provided and encouraged to solve practice questions & quizzes provided at the end of each topic.
