Is this oneshot enough?

I have only studied IOC in Organic Chemistry so far. Should I complete GOC from this oneshot?

I have some doubts:

  1. Is this oneshot complete, and is everything explained well?

  2. Can someone who has never studied GOC before understand it from this oneshot?

  3. Someone mentioned in the comments that reaction mechanisms are not covered. How should I study reaction mechanisms? Are they really that important?
