Adda247.com is a website where they provide contents for govt exams, bank exams with videos, test series, paid classes and ebooks.
My views : Recently, I wanted to prepare for railway exams and decided to check out this website and their youtube channel. Though they started teaching well, but within a week some of the subject teachers went missing and after nearly a week, new teachers were assigned in their placesand classes were started from scratch.They provided contents which I found not upto the level of such exams. The test series they provided were decent but not great. The ebook contents need further improvement as I found some misprints.
Conclusions : I shifted to other online teaching platforms after finding this site not so reliable and I will recommend others as well.
