Dear Aspirant 

First of all Congratulating you on your nice performance and I would like to tell you that based on choice of two colleges provided above, if you were to take my opinion, I would suggest you to take admission in Jadavpur University because this university is ranked above various iits and nits in terms of everything and is one of the best college in West Bengal, at the same time mechanical engineering is core branch unlike information technology so, go for it. 

Good luck for your counselling procedure :)

Feel free to ask if you have any further queries.
