One should opt for online/conventional course. This helps in understanding concepts. It is advisable to join a coaching where personalised attention is given, i.e. not more than 20 students sit in a class at a time. The classroom course should be supported by textbooks/course material. It is better if the course material includes recordings of the classes as the student can go through them repeatedly if he/she has not understood some point in the class.

Course material designed for IIT-JEE in the form of eBooks or hard-copies is also useful.
