  • Hi everyone , I am new to this online learning course and i am in 10th class . I tried this course to check whether i get free certificate or not and i was happy when i got it .
    about the course i must tell that all the geometrical concepts are taught with deep theoretical knowledge and examples , some concepts were not clear when i studied them in my school level but now every concept is crystal clear . I really enjoyed this course and now i will start another course soon . I love Mathematics and wishing to explore more knowledge , Thank you so much for providing such deep information free of cost , Loved it .
