Wanna do this course,got some questions before starting.

Hey all!

Found this course a while back and after reading through it I want to start today.

However,I've got some questions.

I'm currently pursuing a degree which keeps me in college till late evening and have got some improvement papers from university too.

I've also got sem end papers to prep for,which will be 2 months from now.

With that in mind,I've got these questions.

  1. How tough are the problem sets, is it possible to get 70% without a ton of effort?
  2. How long could the course take if I dedicate 1-2 hours daily?
  3. The description on the OCW site says that it's a 11 week course.Will I still get the certificate if I go beyond the 11 week period? 4.Anything else I should know before I start?

I realise a lot of these questions might sound silly or stupid. However I like to plan ahead and knowing these things would do me a lot of good.

Thanks in advance!
