As your score is of 210 marks in IIT JEE 2010, so with these marks your estimated rank would be some where in between 4500 to 5000. According to the calculation chances are less that you can get Aerospace engineering in any of the IIT's .
for aerospace engineering your approximated rank would be under 2200 and for that expected marks would have been 245
And as compared to the last year's cutoff this year this has been predited that the cutoffs will be lowered, as the level of the paper is slightly decresed.
However score may vary and as a result rank may also vary, a slight difference may create lots of difference in rank.
