Is it worth to do course twice?

Question

You refresh memory and you would better understand things, but is it worth to do it again?

Answer 1

i think no.
Do challanges and if you dont understand why your answer is wrong, repeat that special chapter of the course.
That gives you a deeper understanding.

Answer 2

Honestly, you'll find it so boring, but trust me, its worth it.

Answer 3

Depends on how well you understood the material the first time. If you knew the answers to all the questions, you probably won't learn much going through a second time so don't do it. If you had trouble with the questions, there is a huge chance you missed information that didn't get asked so going through a second time is well worth the effort.
