Which is best Online coaching for Essay?

Ramaswamy was there few years ago. Don't know if he is still there. You can try Vikas Ranjan, though last year some students got low marks with some of his approach points. Shabeer Sir takes some classes,  but test series is not there. The classes are good for one time watch. Forum also has essay program. They have some classes also woth it, like Shabeer Sir model, but we don't know how it is. Last year when I attended the classes happened after the test, this year they have classes before essay. You can consider it. If you have not done any test series, you can go for Vikas ranjan or forum. If you want essay class go for Shabeer Sir.
