Hello Aditya Pathak. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

I understand that you may have some difficulties in writing WBJEE because you have to travel to West Bengal just for this purpose. UPSEE is a more feasible option location wise. 

But, I have no preferences over one another. See, both require that you have a thorough grasp of all the NCERT/CBSE topics of class 11 and 12. 

It all depends on you. Just prepare for JEE Mains and you are good to go to write any one exam.

Hope this helps you and all the best!
