Dehradun

well, with a restriction of Dehradun, there is only one good college I can suggest that is UPES College of Legal Studies.
They have diverse range of courses like
BCOM LLB (Hons) with Specialzation in Tax Laws, BBA LLB (Hons) with Specialzation in Corporate Laws/International Trade & Investment/ Banking, Finance & Insurance
BALLB (Hons) with Specialzation in Criminal law/labour law/energy laws
You being a PCM student can take the advantage of coveted courses like BTECH LLB with Specialzation in Intellectual property /cyber law.
In Dehradun there's no other law school this good, offering this many diverse range of courses which have much scope of growth. With the rise of importance of environmental laws and intellectual property policy these are sought after courses. UPES also organises moot court competitions in which all good laws schools in india take part. Research paper presentation & seminars etc are also conducted. all these are benchmarks on which a good laws school is measured.
Normally I would advise a Top 5 NLS but only in case of Dehradun it is UPES. All the best!

On the payment of Rs. 25,000, you will be awarded with a degree of an MBA from IBS Gurgaon. As I keep telling other students, IBS Hyderabad, Jaipur and Dehradun provides the degree of MBA and IBS Gurgaon provides a PGPM degree. You can pursue the two at the same time since the examinations of an MBA will be held in the month of June/July/December/January every year and are conducted on Online/Computer based test mode. As far as your query regarding the two courses is concerned, the examinations for the two will not clash at the same time since the examinations for the pgpm will held in the month of August and December(Mid terms) and September and February(1st and 2nd semesters respectively). All you have to do is-Manage and manage it well.
