As per my experience Mentors Eduserv is one of the worst coaching institution of Bihar. I taken admission when I was study in class IX and they were not able to teach me even the board level. If I talk about the teaching process then this is completely worst. When you go for the enquiry at their office then at that time they speaks a lot more good things but when you will start classes there then after you will came to know thr reality.The most bad thing I experience is that they dont have proper doubt session for the students. They just teach you only thing according to competitive point of view and by this your basic will be not clear.They only put big big hoarding and invest. a lot more on advertisements, they shows that many studenta of our institution hs qualifed in IIT JEE and some of them are toppers but I must tell you that its all are fake and they purchase toppers, they jusy shows their names and faces.If you are planning to take admission in Mentors then I am telling you clearly that just change you mindset and go for any other institute in Patna, there are so many institutes in Patna. Mentors is not a institute but this is a company which only knows their business plan and does marketing with students. If you go here then this will be completely waste of both time and money.One more thing if you are reading here then I will suggest you to join any alternate coaching because they are not capable to make you a IITian.
