Myself Muhammad Yaqoob I am feeling good to tell my review. First of all, I came to know about this wonderful application at reasonable price from social media where I was astonished to see students getting top positions in NMDCAT. So I decided to join topgrade. I contacted with information officer M. Usman and he was very humble and co-operated well with me. First I was afraid about joining this like you are but when I joined it, I found it very useful because the teachers notes are very authentic and to the point. Moreover, I can access to many mcqs topic wise with explanation. So, I recommend you personally to be a passenger of this ship which will bring you to destination. Thankyou
