Testimonials
I have completed my PGD in Piping Engineering from the Suvidhya Institute of Technology (Batch-140).
I feel very gratified that I am part of SIT. The overall experience was very remarkable we were given in-depth knowledge of the subject as well we were thought interpersonal skills. The teachers of the institute are highly skilled and are extremely helpful and always ready to assist you with your doubts. As the world is facing COVID 19 pandemic, the institute didn't pause our training however the whole training was launched online and was as good as the classroom program.
The one thing that inspired me and make SIT distinct from other institutes is their regular Assignment and Tests which keeps students well on track of the subject. If someone is thinking to pursue PGD in Piping Engineering from Suvidhya Institute of Technology I would highly recommend providing he/she must be eager to study the subject. I would like to thanks all faculty of SIT especially Mr.Vasant Mestry Sir for his immense efforts and making us ready for our future endeavours.
