Your statement “You can get an A+ without a single proper sentence on a law school exam” may be true to your experiences, but mine are 1) there’s no A+ in law school, and 2) writing ability is the primary factor in a grade. It’s not merely what you say, but how you say it. I’ve never seen an A exam answer with clearly improper sentences (with the exception of one professor I had who had strict severe word limits).
1. Law schools have A+. Perhaps not every one, but most do.
2. Writing ability is the least factor in a grade. I have been shown A+ exams from top schools with misspelled words, broken sentences, and horrific grammar.
Even in the best law schools, they give homework and tests and are competitive about grades. The best yeshivos have bochurim sitting and learning for hours- the motivation comes not from grades or tests, but from within.
1. Law school does not have homework.
2. Law school does not have tests–just one final at the end of each semester for each class.
You don’t seem to know much about law school.
I know many BTL grads who have issues in Grad School with writing skills, research skills, ect. They have needed to take some remedial classes.
Let’s talk about law school specifically, not about generic grad school. Nobody coming to law school knows how to do legal research (except the former paralegals perhaps).
