Signing up was easy enough and I was able to look over all the topics/notes in the free trial so I knew exactly what was being covered and if some of the important topics had good enough notes for me. Payment and starting a course is very easy, I contacted them through whatsapp and they gave me all the details for payment. I used easypaisa and was up and running within an hour. Their response time is very satisfactory and you can also just call them up. I would very much recommend that if you find yourself in the need of an online course that can get you started almost immediately and conforms to your own schedule, that you try TopGrade. My parents were also wary about falling into an online scam, but I can assure you otherwise.
