Hello 

The first thing that you have to analyse is the career opportunities for both the fields 18,628 is a good rank and your brother may get admitted to collages which are around top 20 to 50 and engineering has a wast scope in terms of jobs as well as pay I suggest to take CS or Civil or Mechanical branch as they are ever green branches in engineering and after engineering if he wants to continue studying he may also chose to take Mtech, MS in abroad or MBA, comming to BSC LLB it also has a wide range of scope he can also study masters and become a lawyer if he has a critical thinking and love towards laws and the main important thing is emory power to remember all the sections and it completely depends on him weather he wants to work under someone or work as a lawyer. 

Thank You
