I have already taught aptitude in IMS Engineering College, Ghaziabad for campus placement purposes. I shall provide a demo of 1 day free. Usually, I charge around 800 per hour. A good preparation time is 40 hours covered in 20 sessions of 2 hours each. That can be reduced to maximum 24 hours with 12 sessions of 2 hours each, covered in 2 weeks. Let me know the project in detail if you're interested.
