Thanks for the information because i do not have any information regarding legality about them, because that were provided me one of my friend and i have no idea about them,and since SCJP takes so much hard work and dedication, so whatever i got i tried to practice like with all other mocks i was doing, and as everybody does if he was in place of me. but since whizlabs are aithorized so i bought them from whizlabs that were very useful,
but again thanks for the information so i can suggest to others, so that they can save themselves going in any type of any trouble.
Thanks a lot.
