Both Mechanical and metallurgical engineering at Thapar and PEC Chandigarh have their own pros and cons. Let's list them out to opt for the best college for you. 

PEC Chandigarh:

• PEC Chandigarh has a better brand name compared to Thapar University. But Thapar is surely not far behind.
• PEC has an amazing culture that prepares its students for future career challenges.
• One can prepare well for their further MBA, Mtech, or MS entrance exams while being at PEC Chandigarh.
• Being a government college, PEC is doing a great job in its placement department. There was a 28% hike in their placement record in 2020 despite the pandemic situation.

Thapar University:

• Thapar has an amazing placement record and coding culture.
• As a brand name, it's growing up to the heights of PEC.
• If you opt for metallurgical science, you will limit yourself to few core companies or steel and other manufacturing firms.

Unless you are into metallurgical sciences it's better to opt for mechanical engineering as you can even jump into both technical and non-technical firms. 

Quick comparison:

Out of the above two, ME at PEC seems like a better option. PEC being a government institute has half the tuition fee of Thapar University which saves you a lot. If you plan on an MBA further, it's better to opt the best out of two and start preparing from the first year of your college itself.

Both the above colleges are really good, so you needn’t worry about that front. You need to first decide which field you have an interest in. If you really have an interest in CSE, only then you should go for PEC. Otherwise, mechanical is a very good branch. Moreover, DTU is known for its mechanical department.

If you are really interested in either of the branches, you should go for it, irrespective of the college you choose. You must first check if you are interested in coding/ development or automobiles, etc. But if you can’t judge your interests, you should go for DTU because Delhi life would offer you more exposure and opportunities. DTU Mechanical is an old, developed branch that is very proud of its heritage. 

The table below gives a brief comparison of the courses.

You may ask a DTU as well as a PEC student for their reviews and then decide which college you would like to go for.

IET Lucknow is among the top-rated government institutes in the country and it is being affiliated with Dr. Abdul Kalam Technical University (AKTU). 

Ramaiah Institute of Technology (RIT) formerly known as M.S. Ramaiah Institute of Technology is an Autonomous Private Engineering Institute located in Bangalore affiliated to VTU.

The fee structure of both of the colleges is as follows.

The facilities offered at both institutes are different. The student can explore themselves better at RTI due to its location. Bangalore will offer you much more placement opportunities than at Lucknow.

If you are interested in coding and aim to work in good corporate firms, then it is suggested that you go for CSE at NIT Calicut. But if you want an IIT tag, you can opt for IIT BHU. But this won't matter much afterward.

So, if you are focused on doing research then Chemical Engineering at IIT BHU will be a good option. You can also learn coding on the sidelines, which might be beneficial if you sit for placements.

The choice of studying in a college pursuing a particular subject is entirely up to you. Check where your strengths and weaknesses lie and then choose accordingly. Both institutes are good in their own way. But it is your hard work and dedication that will prove if CSE or Chemical will be good for you.
