Hi! for 10 + years I have been taking aptitude classes. Quantitative aptitude, logical reasoning, data interpretation and verbal are taught by me. Have gone to more than 500 engineering colleges (mainly) in India. I have also worked for institutes like TIME, Vista Mind, Aspire, Smart etc as faculty/trainer and took classes for CAT, bank coaching, placement, GMAT etc and I expect to be paid Rs. 5000 per day.
