MO is an acronym for Modern Orthodox.
And about law school vs. OT or PT (which now requires a PhD IIRC): while the former is more vigorous the latter still takes some serious smarts and commitment and results in the kind of over-education the OP referred to.
And about women learning, gemara or otherwise: There are many serious learned women in the BY world, and I don’t mean gemara. They have the kind of curriculum that used to be offered the boys in terms of well-rounded nach knowledge, as well halacha l’maaseh, hashkafa, and history; and the ability to learn sifrei hashkafa inside if they’re so inclined. And, many women now are fairly committed to continued learning, formally, in classes, and on line or on the phone. Again, even without gemara, resulting in very educated young women, which could be intimidating.
