[Closed] Some help with Google Analytics?

Hello!
Can anyone give me some help with Google Analytics?

A website I am working on has had customers reporting some bugs with our login/registration forms and booking forms for events and courses we sell.

I would like to track how many people are getting to the forms then giving up/leaving the site.

It's been ages since I've used Google Analytics and it has all changed! I can't find this in the help either.
Do I need to set up Goals, e-commerce reports or look at the User-Flows or something?
