Hello Sir. Dual degree programs are fantastic when you are clear about the specialization and want to make a career in the select specialization.

Check before you choose the dual course:

Curriculum (Does the cover themes/topics that should be covered in the MTech program? or it has a different curriculum? Does curriculum offer practical experience, industry exposure?)

The focus of the program (Is dual program is industry focused or research focused?)

Faculty members (Are they expert in their specialization, have good research publications?)

The exposure you get in the dual course (is it equivalent or at par with regular MTech course?)

Placement (how is campus placement for a dual degree program?)

Does the institution offer a Ph.D. program?

Benefits of Dual Program: 

If your goal is to do MTech after graduation, then the dual program can save one year and also save you from giving an entrance exam for MTech admission.

Dual degree program would be very useful if you plan to do a Ph.D. or enter into academics.

Several multinationals have set up advanced R&D labs in India, and they hire MTechs and PhDs only, giving a very good work environment and a lucrative career. The dual course will help you get into those labs.

The placement of IIIT Allahabad is very good and the packages offered are also very good.
