ANY REWARD OR PRIZE IF WE WILL GET RANK IN CPT?

no dear,

 getting rank is award in itself

Just an advantage,which may help u in future...an achievement,that could be mentioned in ur Resume in future.

Yes For 1st Rank - u will get exemption in PCC registration fees as scholarship.

and some low amount for 2nd Rank

No exemption for 3rd onwards.

Work for it dude....even the time spent on this research is a waste of time if u r preparing for CPT...close internet ......go make some contri for ur exams.....the researchers always are excited by the statistics (of the results of others).. and every other trash stuff ...they goes on doing research.....
