I thought of doing a data science course, so I searched for data science online courses. I also had a talk with some of my seniors and I was suggested various platforms, Topmentor is one of them, I joined Topmentor from their reviews on their site. Unfortunately it was my biggest regret and mistake to join Topmentor for a data science course. The instructor is not very knowledgeable and has less experience of teaching. They don’t start our course from the basics, just start from their own  mood. They only cover syllabus and don’t concern students’ doubts and skills. The faculty is very bad, their supporting staff and mentors do not help students in any matters. They do not cover the practical knowledge of individuals which help students easily in their learning process. Also not covers the projects and assignments. Topmentor also does not assist you in your placement, and has the worst HR team who is not more concerned about your career. From my personal experience I would suggest you not join Topmentor for your wonderful career. I hope my feedback helps you to find the best data science course.
