Eli Y,
“The point is that for whatever reason, he is not fluent in Hebrew and will not be because it is a lower priority.”
Writing as a BT myself, if at all possible, make this a higher priority. Better skills to learn chumash, mishnayos, gemara, rashi, tosafos, shulchan aruch, etc. inside is something I always wish I had been able to get at a young age. Do it with him if possible!
