B.Tech

Some recommendations are LPU, Chandigarh University, Amity University, CHITKARA University, VIT, Manipal, BITS, SRM, etc. Other than first four, rest do not even accepts JEE Mains with lower marks, they have their own entrance. Moreover, you can get into first four having good placements and suit your needs.

Yes, it is going to be difficult for you as you are a science student. It will take some time but if you are a brilliant student then marketing would be easy for you if start learning about basic. Good Luck.

Ater Diploma you will get admission in the 2nd year of B.Tech in the same branch as of Diploma. You have to fill up the form (Online / Offline ). Admission is through counselling based on the marks obtained in Diploma.
Best of luck. Thank You!!

If you want to do B.Tech, there are so many fields you can choose. The top branches are EC and CS. Both are most demanded in the modern era for the embedded and computerized system. Well, other branches are also good, taking a field totally depends on your interest. Select the one according to your interest.
All the best.
Thank you.

Hello Swapnil,
I think WBJEE was conducted for fresh admission to the 1st year engineering in colleges across WB. But you are seeking admission via lateral means directly into the 2nd year. WBJEE score will not help you. You will have to follow the centralised system of DTE (WB) for this.

Hello Aditya,
Yes indeed. Mechanical branch is one of the oldest and still continues to have great potential for jobs.

Dear Rishab,
The major things which you should keep in mind while choosing a B.Tech college are its placement record, recognition by different institutions, easiness of transportation, fee structure, infrastructure, variable courses availability, and various scholarships provided by the institute. If you are interested in sports and extracurricular and curricular activities so the list gets prolonged. Take a good decision while shaping your career.

Dear Santhosh,
Happy to help.
Aeronautical engineering is deemed to be a great branch and has vast scope in the future. But here there is a contradiction about the performance. If you are really a fast learner and aspiring a job in skill based. It's a bit difficult. I want to include some points that after pursuing BE in Aeronautical Engineering, you may not surely go for aeronautical engineering but you can opt for other government services.
Hope this helps.
