For CSE, NIT Uttarakhand is a decent option. Given below is a brief review of NIT Uttarakhand.

Criticism:

• NIT Uttarakhand is in a remote place, away from the city. So if you are not used to living an isolated life, it will be difficult for you to adjust. Even traveling to Srinagar Garhwal will be difficult.
• The infrastructure of the college is not that great to appease you. It will feel dismaying. It is improving gradually.

Brownie Points:

• NIT is a brand. It has special importance and value to the nation. The CSE branch is always advancing and can add special talents to the industry. In this institute too, there are many talented students.
• The faculty of the institute is from renowned institutes like IITs/NITs. The professors are highly qualified and teach students proficiently on-line with the GATE syllabus.
• Students are from diverse backgrounds. They are not just from Uttarakhand, but also all other states.
• The placements of the CSE branch are elevating every year. Different recruiters give different offers to students. The recent placement statistics of the institute is as follows.

• Many companies give internship opportunities with PPOs to the students too.

No matter how much the infrastructure lacks, the students get rewarded in the future if they work hard. Currently, IIIT Ranchi and Thapar may have better infrastructure or even placement records, but NIT Uttarakhand is improving with time and will definitely improve a lot in coming years.

You will have to write an application to the deputy registrar of Academics. Alternatively, you can also send an email to Deputy Registrar with your application.

As far as transcripts are concerned, you need to send the complete address of the universities for which you are applying. Along with this, send two sets of your mark sheet photocopies and degree certificate.

These sets should be authorized by the college and the other set should be duly notarized by a legal or commissioner of oaths or self.

Lastly, your transcripts will only be sent once the administration receives the photocopies of your mark sheets and degree certificates. Overall, it is a pretty simple process. Your work should get done smoothly. 

Among the above institutes, PEC Chandigarh is the best choice, considering the factors of availability in streams, fee structure, etc. If you have a specific branch in mind to pursue, then you can definitely choose PEC Chandigarh. But if you are considering a non-IIIT or non-NIT tag then you can opt for DTU. 

The table below gives a brief level of comparison among the institutes.

Key Highlights:

• PEC Chandigarh is a government institute and so has a much lesser fee as compared to Thapar University, which is an autonomous university having a much higher fee structure.
• There are some subjects in PEC Chandigarh which are not available in other institutes like Thapar University or CEG, for example, Aeronautical Engineering.

Therefore, PEC Chandigarh is a better choice considering the factors stated above. Other than these, all the three institutes are incomparable to each other as they offer similar quality placement.

I know a few things about LNMIIT since I have few friends there. It is a public-private non-profitable college, located in Rajasthan. From what I heard from my friends, I will not recommend choosing this institute. 

• The main problem of this institute is the administration. There have been many misconducts by the management, in recent years.
• Scoring marks in college is very hard as the teachers usually give D and F grades to their students which makes their GPA < 6 and hence making it difficult for them to sit in the placements.
• There is nothing like supplementary exams which is common practice in IITs and NITs.

If you want to build upon your career, don’t choose LNMIIT. Mostly, half of the batch fails in the exams.

Finally, life is tough at LNMIIT, so don’t go for it. Look for other options.

Some of my friends studied at Thapar University. According to them there's definitely no uniforms in Thapar University. 

• However, the first year students who have a 'khaki dress' will have to wear it for workshops. 
• This is compulsory not only for BE but the rest of the branches as well.
• As an omnipresent rule for science programs, you'll have to wear a white coat/lab coat for some M.Sc. projects or practicals.
• No need to worry about it being a daily state of affairs. 
• At times you'll have to show unity with a uniform as well, such as to affirm your stand for cultures through the Saturnalia and for technical stuff through Aranya. 
• These fests include modelling shows and you might want to join in and showcase your skills. 

A uniform might be needed for these. Sometimes a faculty member might ask you to be in formals, they do expect that, but no restrictions as such.

If you are not liking your college life currently, there are a few options you can explore. These could include any of the following:

• Look out for research options. See what your faculty is working on. This may get you interested in something. 
• Summer internships are also quite popular at universities abroad. Choose a subject you like and do a semester abroad if you are interested in that.
• If you want to enjoy your college life, you will have to break the ice with members of different clubs. Nox is a good dance club you can think of joining.
• Get in touch with your seniors and super seniors and see what they did during their time as a student. Maybe that should help.
• If you are not that interested in studying, you should consider that option only if you want to do something completely different from engineering. 

You should find your calling and pursue it. This will help you truly enjoy your college life and you will not regret your decision.
