CMS 2 (certified exam)

Just passed my level 1 yesterday day. Looking to further my certification because I found a lot of joy in studying wine especially noticing how my confidence levels increased while talking about wine to my tables and selling it. For those of you who have taken your level 2 how do you suggest I study to be confident and proficient for the exam? Got 87 on CMS 1 if that gives any insight to where I’m at knowledge wise lol any tips would be much appreciated.
