meet up with him a lot, until he invites you to go to an event with him on the weekends. that's really the only way, he spends his time in the gardens and studying in the library and classroom. when skipping, just go to the library. also, make sure you go to both history of magic and pratical 101. during curricular activities, be sure to go to workstudy in the kitchens. try it out if it works :D
