Mechanical Engineering

if u r worrying about placement then it is okay. both the colleges with there respective branches taken into consideration have good placement records. now it solely depends on Your interest. Mechanical engineering deals with mechanics and material Science, computer Science deals with computers. but what I feel here in India when u study car they don't teach any industry related courses like android php phython etc. u can do engineering from any branch do some industry related computer courses and u can be computer engineer that is truth. so go for core branch like Mechanical, civil, electrical, electronics.

mechanical branch has better and more job prospects . the situation is like a concentric circle . mechanical branch is the outer circle. electrical is the inner circle.

You are eligible to seek admissions in BCA . You may seek from your institute principal equivalence of diploma to 12th class. Why do you want to do BCA? You are advised to seek lateral entry admission in B.Tech in branch of your choice.

Scope of mechanical is good but in terms of placement in JSS Noida its not that good, only fraction of class students get placed through campus this time few that visited for mechies are Honda , Anglo-Eastern ,some designing related(Auto CAD, Solidworks)etc. And average salary is about Rs.3.6 lakhs p.a and rest crowd go for GATE exam, off campus placement ,other government services. JSS is good college have decent crowd and faculty with good labs.

Since you have already started studying in Swami Vivekanand Institute of Science and Technology, you must ask this question from your seniors. They will be better equipped and informed to answer this question for you.
My suggestion is that rather than worrying about placements, focus on developing your skills. Do new courses and learn about new technologies. When you are well prepared, you will not have to worry about placements from the college. You can get a job off-campus. All the best!

it's depends on your interest and your skills. girls can take admission in mechanical branch if they have this types of attributes.
