Best time to look over and learn ethics?

I’m planning to take mocks but will be skipping the ethics portions because I haven’t even looked over it yet. Should I review it during the final week of May right before the exam or is it better to approach it differently?

I started studying January 18th. Just started reading ethics in the CFA book on Tuesday.

Best time to learn Ethics: from about age 3 through the date of your last Level III exam.

Best time to review Ethics: the last week before each exam.

The best time to review ethics is during the last 2 weeks before the exam .
