I had bought a course for bank po exam from gradeup after I had a poor experience with testbook app. First of all I would like to mention that my review is totally based on the bank exam courses that they are providing and no other courses.
From my experience gradeup provides the best online coaching courses for people who don’t know hindi and are looking for classes in english. Their online classes are top notch and the teachers who are taking the class are pretty good in explaining the portion for the exams. Even if we have some doubt regarding specific portions we can always apporoach them and they are always willing to hell with it. They provide course package in both hindi and english medium. Their course packages are also at a reasonable price and are included with mock tests which are very helpful in practicing the topics.
Overall, gradeup is the best online coaching team that I have come across and I would totally recommend it to anyone who is looking for online coaching classes.
