hey kunal 

suggesting you exact rank range is a difficult task. websites usually predict rank on the basis of previous year marks. but no.of candidates giving exam increases every year and so is the comptetion. i would suggest you  to wait patiently till the results are out. untill then you can have rough idea of ypour rank. no one can provide you exact rank range.
