Colleges in Haryana

Based on your rank, you might get admission in CE, but I can't say for sure. You should apply for it though as there is a chance that you might get a seat during spot round.
However, if you belong to a reserve category, then your chances improve significantly.

YMCAUST does not offer CSE. Instead, it has computer engineering which is more or less identical to CSE. Also, YMCAUST is ranked higher than DCRUST in Haryana, so if you have a choice, go for CE in YMCAUST.

If you don't belong to any reserved category, it might be difficult for you to get the mechanical stream. However, there is no harm in trying and if luck favours you, there might be some chance during spot round.

Apply online for Haryana counselling which is supposed to be starting in June. Carefully, go through the brochure provided on the website. Apply and pay (if required) for the reserved category.
YMCA takes applicants through Haryana counselling only.

I am sorry to say this but I don't believe you can. However, there is no harm in trying and if luck favors you, there might be some chance during spot round. You can also apply for information technology as your second choice.

I would suggest for JKBS as it has very good faculty who are graduates from IIMs and other top colleges. JKBS provides you a lot of opportunities. The environment around JKBS Campus is very nice which is pleasing and creates a healthy environment for study. It also provides you various industrial and international exposures.

Our college is really good as compared to the other college in terms of infrastructure, placements, students, facilities provided and events, etc. But the college is not located at a convenient location, it is far from the metro station & there is no place to hang out nearby the college. It is among the top colleges in Indraprastha University. According to the IP status, the college is quite good. It is value for money and the average package from college is Rs 3 - Rs 4 lakhs per annum.
