The other exams have more or less the same pattern except in some, mathematical aptitude is not required. But the patterns and syllabus keep on changing. So do a good research before going for it. And lastly a piece of advice that, don't just go for every single law exam. It will ruin the quality of your preparation. Have some set goals and prepare accordingly. It would yield you better results and won't ruin much of your time or money. Obviously, the choice is yours. Most of the colleges or universities that offer courses in law have their own entrance examinations. One of the most recognised examinations is CLAT which stands for the Common Law Entrance Test.
