See you are in  10th class so you may not have the clarity about what you want to pursue. Now as you mentioned two fields then I think you are feeling a bit interested in both the fields. But both the fields are different so you have to choose one. Now what can you do.

For studying law you have to Undergrad then LLB. Now as you said engineering then you have a eagerness in science. So you can choose science in class 11 , 12 . You will read the subjects and you may not get the essence of Engineering but you will atleast know how studying engineering can be (you can think atleast) if you don't feel ok with engineering you can go for Law after +2 or any bachelors degree. Even if you want you can study law after a BTech. So it's upto your interest.

I would recommend you to investigate about both the subjects and try to analyze by your own. You have two years to explore and I am sure that its enough for you to decide.

I hope my answer helps you. All the very best for your future endeavors!

Hi,

You can choose any of the stream you want as per the area of your interest. Both these fields are of totally different arenas. Engineering deals with the technological advancements while law has more static portion and is studied to protect the laws and regulations of the country. So, you should do any course based upon your interest. Choosing any course randomly just, on the basis of scope will land you in trouble. So, discover your hidden potential and know which field attracts you more. Both these courses have well established esteem and scope in its own field. Try to do bets in the field in which you carry skills. You can do LLB if you choose law and B.tech in any of the specialization as desired by you.
