hi,

see bits pilani offers  M.Sc. (Hons.) in Biological Sciences, Chemistry, Economics, Mathematics and Physics, which comes under integrated m.sc course, These are integrated degree programmes without any related  B.Sc. degree.  students who are enrolled  for these programmes  generally  work for a second degree from B.E. (Hons.),  B.Pharm. Degrees under the dual degree scheme. so I dont think you would face difficulty at placement if you prepare yourself by learning latest technology and soft skills for corporate sectors. but dual degree course are mostly research oriented , you have to keep balance between studies and devote your time separately for academics and skill development.

hope you understand.  choice should be yours to take year gap or take admission this year.

Incase you dont get CSE at Any Campus of BITS Pilani, you may perhaps take up M.Sc. in Economics or Mathematics in First Year. In Second Year, you have good chances of securing CSE, provided youre focussed and dedicated throughout your First Year. Other option maybe, pursuing ECE/Electrical at some Campus at BITS Pilani, which is equally good and has good Placements, you can always specialize and develop your interests in Software Development, ML or Data Engineering.
