Topgrade academy is a legitimate online learning system. I was surfing the internet for online academies for my upcoming NETs when I found the website. I signed up and the academy representative approached me via call. I was given a free trial. I took some lessons and did tests. The video lessons are to the point and cover up the topics of my NETs. The sir guided me throughout untill I got the hang of the system and replied to my queries all the time. I liked the working algorithm. First you take the video lessons, then go through the notes and do some questions which keeps me motivated and track my progress. And now I think I can actually ace my NETs because firstly it is not costly and it encourages you to work independently and do self study. That's how I know my mistakes and where to make myself better. Investing in yourself never goes to waste and Topgrade is the right place to do that!
