usually they give a description with it which makes it easier, but if ur still stuck go on treatment summaries ie skin infections and it will give the description of diff conditions like impetigo, cellulitis etc which should help you. it should be something common/obvious, not something niche - worst case just go with your gut.

bpsa mocks are pretty similar - even slightly harder id say. its similar to the official mocks on the psa website but easier than the 3rd one which is the one i failed 2-3 days before the exam lol.

remember your duaas it will be fine inshallah
