Hi,
This is a very relevant question.
I live in Pune, India.
Apart from the monetary issue, I also face one more challenge: Finding the right class.
There are so many coaching centers available and I keep on getting mixed reviews about them.
There is one very popular GMAT class which has a class strength of 100+ !!!
Others do have an acceptable class strength of 5-15 students/batch but then one can never be sure of trainers when you keep getting mixed reviews.
I strongly feel that if the right coaching class is not selected, I may end up losing time as well as money. And as a working professional, time is very crucial for my career.
I would say that online classes are a better bet than offline classes(although costly).
As of now, I have decided to start self-study after office hours. I am relying on
Manhattan books(for verbal) and Nova(for quant). Got the resources from a senior

But later on, I do plan to join an online/offline test-series to remain competitive and identify my weak areas.
Any suggestions on my methodology are most welcome.
