Part-Time Benefits Questions

Hey everyone,

So I'm 34 and just started at Walmart part-time, I've had seizures before in my childhood so this job is perfect for me and I'm back home in time I can take nighttime medicine. I'm just wondering I'm new to the part time life and what are the benefits like can someone give me a timeline of when I'm eligible for stuff? I am also considering using their education benefit to do a BA in computer science. I've only been here for a month. Thanks in advance.
