Need help with first bus tickets

Hi! I’m starting a night shift today travelling from Maryhill to Bishopbriggs. I will have to take 2 busses to get there and 2 on my way back. I’ll be leaving around 8.30pm and returning 7am the next day. I’m confused on how the bus fares/weekly bundles work. My shift is 2 days a week. Does a day pass works for 24hours? What bundle would be the most cost effective for me? I’m also a student but above 22. Please advice! Thanks x
