School supplies + Fashion

I'm someone that struggles with staying on track and be organized, i would like some tips on what kind of agendas or calendars y'all recommend so i can actually improve in being organized. I usually do all my work last minute and it's not very ideal since im a university student with 5-6 classes. Asides from that, I kinda wanna get recommendations on fashion. I dress very alternative, ion wanna say im emo or y2k cuz it's a mix. I just wanna know some good brands also for shoes because i've been wearing these boots like doc martens for yearsss and idk what kind of shoes are nice or go with my style.
