Level 1 Exam in 12 Days not sure what to do. haven't touched ethics.

I have my exam in 19 days and i am not sure what to do. I have read people here emphasize alot on giving mocks and checking your mistakes but I havent had the time to do so. I work a full time job in audit and was barely able to complete the syllabus last week. I have been revising stuff this entire past week because i just dont feel confident enough to give a mock.

My main question being (a) how long does it take to do ethics? (b) is it a good approach to give the 2nd part mock first (since i have those sections revised) then revise the other sections and give the 1st part mock after i do ethics? Not sure if i will have time for a 2nd mock though. Any help will be appreciated. and i am took these last 2 weeks off from work so i can focus.

Also any other free mocks i should give instead of the CFAI ones? i head Uworld is good?
