I would love to invite somebody interested in this course to take it. However, is it too late for them to join today and get the certificate? I will of course invite them anyway because the material has been useful and well taught in my opinion thus far, but certification can’t hurt! 
No, I’m sure if you email Aakash, he will get you on board just fine. Cheers!
I have shared this course with my friends and they’re enjoying it 
I think if you want a certificate of completion you have to complete all the assignments and the first assignment submission date is gone over, but you can check with Aakash he’ll help them.
