This is great website and I am sharing with you my expericence so let me tell you something I did c programming course from this website and I also pass the test with 80% result.
But I don’t get any certificate and the certificate is very costly.
So don’t waste your time on this website.
I did my c language course from this website and there were no coding in this you can get only general knowledge about c.
I think you should not spend your money and time in this site.
If you complete your course on this website then you will not able to even see your certification.
Personally I don’t liked this.
