About scjp 1.6 exam

hello friends,
i am going to give ocpjp exam next week, i am prepared for this exam but i am weak in computer number system conversions like
decimal to hex and other so can i expect any questions in exam like this because, i have seen this questions only in old mock test
but not in new.
and also can i expect ^ operator in exam
eg. result of 25 ^ 12 ?

Hey! Relax, you do not get questions on conversions from one format to another and also not on binary operations. I think the K & B book has clearly mentioned that. So worry not! And all the very best

you wiil not get any conversion kind of questions.

don't worry Go for SCJP6
