How was wbjee 2019 as compared to 2018 ?

Hello Debasmit,
The question paper of WBJEE 2019 was comparatively easier than that of 2018. This year, some previous years' questions were repeated too.
Also, physics was the most easiest part followed by mathematics and then chemistry. Last year, however, mathematics had lengthy questions. This year organic part had some good questions. So, overall, you can say that this year you could score more marks than last year, if prepared well.
