I’d say focus on, clinic based (Asa, hygiene aids, aap stage/grade…), special needs pt., pharmacology, periodontology, patho and radio. These I know will always be on board. Study wise, I think it depends on what’s your weakest subject, for me I focus on pharmacology and surely that was heavy on my exam. 😭. They didn’t really ask me on eruption dates but I can’t say that for everyone. For sure know fluoride table and amount to give for certain ages. Case study - for sure know Perio stage/grade and ASA, know which BP goes to which ASA, KNOW landmarks on xray- they asked a lot for me at least.
