Dual Degree in Mechanical Engineering: Is it Worth It for My Son?

Respected Sir/ Ma'am, My son appeared in JEE Main and scored 97 percentile this year. He also appeared in WBJEE and got rank of 1500; appeared BITS and got 230 marks. In JOSAA counseling round one, he already got Production Engineering in NIT Agartala and has potential to move to Production Or Mechanical in NIT Jalandhar Or Jamshedpur in next few rounds. Basis his rank in WBJEE, he is expected to get Mechanical Or Production in Jadavapur University. Basis his number in BITS he is expected to get Msc Physics with Dual degree of B. Tech in any Engineering stream (but the engineering stream will depend upon his performance and cgpa achieved in first year of Msc Physics course). Considering the same, now he has 3 options: 1) Get admitted in NIT Agartala/ Jalandhar/ Jamshedpur in Production engineering; 2) Get admitted in Jadavapur University with Mechanical/ Production Engineering; 3) Get admitted in Msc Physics 5 year course, study hard to achieve good cgpa in first year so that he can get good Engineering department as B. Tech from second year, complete course for 5 year with dual degree. Which option should be best for him. Is dual degree from BITS Pilani Hyderabad worth of considering 5 year course, very high course fee and uncertainty as to what Engineering stream he may get in second year for B. Tech. Please advise. Thank You in advance.

Hello sir Are the dual programs successful? BITS is doing collaborative programs.2 years india and 2 years abroad like Buffalo or Iowa or Rmit.should my son consider taking this program
