pt ,appt high means promlem with both internsic and extrensic pathway
only pt is high then extinsic
only aptt is high intrinsic

Yep, PeT and PiTT is how I remember it. Am I lazy and a sucker for mnemonics? Wait, don't answer that

I agree. Some HY ones to know are:
Hemophilia A - inc PTT
Von Willenbrand disease = inc PTT, inc BT (bleeding time)
HUS = dec platelets, inc BT
warfarin OD = inc PT, inc PTT
Vit K def = inc BT
Please correct if I'm off, and add to the list
