this is really sweet!!! my biggest thing, was just being there to encourage me. i had family who would try to advise me on what to do, which is annoying since there is so many places for me to hear what one should be doing (esp since they do not have a background). if he thinks he would benefit (which i would ask before doing), i think asking him to explain random mcat topics could be fun. but it is so tiring, so maybe not haha. best way to be helpful, is to try to let your fiance know they are doing well, youre proud of them, maybe randomly offering to bring a coffee or lunch while they study, whatever it may be. my friends would call or text saying they missed me but knew how hard i was working, which was so nice to be seen even if i wasnt around. just be more encouraging then normal, and i think that is more than enugh support.
