I’ll address the BTL part.
I guess your asking because you have some delusion of using it to go to law school.
If that is the case, it is a very bad idea. You will need to score in the top 1% of LSAT test takers to have a chance at a good school, and even that the good schools, half the graduates are not getting jobs in the big firms anymore.
And unlike other jobs, in the legal field, if you don’t get a job in the big firms, you make about a quarter the amount and still work the crazy hours.
Plan your own life, but yeshiva —> law school, is not a good plan.
