my friend is expecting around 200 in jee, around 66 - 70 in each subject.. what rank and what branches my friend can expect????

He may get selection with rank 8500-9000.

please tell according to the level of this year's question paper difficulty... also tell in which iit and what branch can my friend can get.

Considering the difficulty of paper of JEE 2011, the cut-off will be around 175 - 180. By the way, questions were wrong in JEE 2011. So, expecting 190 - 210 for your friend, he may get into New IITs for sure....!!
