Hi guys, so today I asked my physics professor if he can write me a LOR and he said he could. But he told me that I should tell him more about myself, because at the current moment all he knows is that I go to his office hours a lot and I am doing pretty good in his class. I asked him what would help him write the letter and he said any extracurricular activities or anything that's important to me. I was wondering if you guys, especially those who has been in this situation before can tell me what kinds of stuff I should tell him to help him write a good letter. Thanks.
