faculty,
according to you which feature should i use while practising sets

should i use adtablity
or difficulty level wise

pls advice

I may be wrong but when Initially I solved sets in adaptability mode the difficult does not change according to you skill level, it simply makes you do all easy sets first, then medium, then hard (I may be wrong)... anyways use manual difficulty settings if you are doing lest say 4 sets per day make it like : 25% easy, 50% medium, 25% hard (1,2,1)..Logic: cat gives all difficulty questions in the exam must one of the set is easy-to-medium level and one is definitely medium... so it increases yiur skill level accordingly.
