Quality over quanity is key here. If holding a position in that club is something you want to do, by all means do it! If it’s not, you’re not obliged to hold leadership in every club at your school. I do think it is good to hold a few leadership positions in clubs that are meaningful to you though. Colleges see right through attempts to ‘pad’ your resume with things that you do just to impress them. Of course the more quality the better!
