My experience with Gateforum was bad enough to give them a one star.
The worst experiences are-
1) First of all, they advertise about GATE+ ESE coaching and are teaching just the GATE syllabus.
2) Only GATE syllabus, but in the worst possible manner. The take classes according to their convenience. 20 hours in weekends and in my case the teacher was not free on a weekend they kept timing clashing with our college hours, which was when I left Gateforum.
3) The study material of Gateforum is also not so good. I enrolled for the Intensive Classroom Program and regretted later. I should’ve ordered postel study course of Made Easy.
4) They teach like a crash course. Only questions and questions. No concepts, nothing.
If you are finalyearite or a pre-finalyearite and preparing for gate I would suggest going for postel course of MadeEasy or ACE academy. Or IESmaster material if you want to go for IES and GATE both for a trail, their material is good for self study and if you are serious about your studies.
Overall, My experience at gateforum was bad and I would suggest not going for Gateforum for coaching.
