Aside from gaining weight, i really gained a lot out of my two years. I got to be in the Holiest Land, near the kotel! but besides that i gained a lot of knowledge from chumash mainly. (because of what i learned i can give you an indepth analysis of the inyan of yaakov and eisav and yitzchak and rivkah! i can also tell you what i had to learn by being a roomate and it helps with getting married.
I went to Sharfman’s and Neve Yerushalyaim. There were many girls who did the same. in sharfmans i taught myself to cook which was awesome and in neve i was able to go to any type of classes i wanted which was great. i also had a chavrusa with a teacher which i gained a lot from. For certain levels in Neve you get a tutor which i made a great kesher with!
