B.Tech/BE through lateral entry (direct second year admission) will be best for you, you have to appear for LEET examination to get a good college.

So, you can get a lateral entry admission for engineering.

Ideally, you should start the preparation in third year. You can take coaching from various institutes. You can also get online coaching for it.

Yes you can. It depends on which college you are applying for.

Opt for the domain that you love the most and are most passionate about and analyze the future work conditions, scope and growth prospects before taking admission
You can also opt for psychometric test comprising of Aptitude, personality and career interest to clear confusion.

Evening or distance engineering courses are not valid anymore as per the latest Supreme Court verdict, hence would recommend you to join regular B.Tech course for better career prospects.
