CBSE 12th

Agriculture is a very good course to choose and pursue. You may want to do B.Sc in diverse available options like agriculture management, dairy science, fisheries, forestry, etc., and thereon Master's degree and doctorate. There is engineering in agriculture, food engineering and dairy technology.

This is a query which can be looked at from various aspects and perspectives. Faculty members of colleges differ from branch to branch in expertise and quality. Once you are sure which branch of engineering and which college and city, the best option would be to talk to alumni of the universities to get the first hand information. Also, check about the lab and practical exposure amenities in terms of workshops and presentations and field trips/internships.

This one depends on your core interest and inherent skill set too. In your 11th and 12th, if you had chosen arts then you may want to continue to specialise in languages, journalism, psychology, etc. If it is commerce then B.Com. ICWA and CA are competitive qualifications you would want to explore. If it is science and you have taken up engineering or medical entrance, then it is pretty clear. If not, B.Sc or BCA would be good. B.Sc has various combination of subjects which you could check and see what suits your abilities and skill set and then make a decision.

Well, if you do not wish to do a full-time study of any course not even distance education and are very clear about it, I would recommend you to consider asking yourself if you want to pursue some of your hobbies seriously as a career say in arts, crafts, music, dance, theatre, animation, photography, etc. If yes, how about a proper certification course or even a Diploma or a Bachelor's degree and thereafter making a career out of it.

You could consider taking up engineering through state level entrance exams if not the JEE. If you are not at all inclined towards engineering in itself, then perhaps consider doing B.Sc or BCA. In B.Sc, you have a wide range of options. Whichever subject truly interests you, pick it up.
