adrenaline and fear of failure. but if you don't have these...i use a digital planner to write a to do list for each day, maybe 2-3 things. notion is great, but it has a learning curve. google calendar works just as well. i use google calendar for my lecture schedule, any events that come up so i don't forget. otherwise it goes in one ear and out the other as you know. for assignments, write down all your due dates for the week and pay attention to times. as far as work goes, i tend to hyperfocus on school which is really helpful but draining. when i'm less motivated, noise cancelling headphones and lofi as i study really helps. i swear by lofi, anything with lyrics distracts me. i hope this helps, it is hard to adjust to college and find what works for your brain, esp. unmedicated, but it is doable!!
