Which course is better - a diploma or NTTF?

NTTF is a better option as my brother secured a job offer, on-campus with a decent salary.

The diploma from NTTF is really superior to a regular diploma. Their curriculum is updated according to the industry trends and needs. You will be given proper exposure through seminars, internships, and industry visits. 

The alumni base is also very large and has well-established connections. It also provides you with the college tag, which you can later use during your representation. 

However, you must be more than an average student to succeed; otherwise, it will be difficult. Hard work and perseverance are extremely important for this. So, if you have that confidence in yourself, do opt for NTTF.
