About Afikei – it’s part of the Darchei Bina sems, of which there are three: Darchei Bina, which is intellectually challenging, attracts bright girls, not necessarily all BY types but very solid girls, is known to have some of the best teachers around (Rabbi Orlofsky and Shira Smiles among others);
Chochmas Lev, which draws on the same infrastructure but is BY, has great teachers and curriculum, hashkafa oriented;
Afikei – kind of a Chochmas Lev for girls a bit to the left
