Hi Valentina, I face the same issues in school too.
If you feel like you are doing a lot of things, have you considered if you really need to do all of them or if they can be done a different way? I find study or work groups quite helpful where we are good at different things, so we take turns coming up with lists of things to complete within 1-3 hours. So in a way I don’t need to spend so much time on lists and just start doing something. We are either doing the same thing or things. Maybe that can help you have an earlier start to complete earlier too.
I had a lot of problems with my workflow too, so I tried going through it with my teachers and classmates using 1 example workflow so they can help me identify areas I’m stuck and how to work around it. My classmates I work with also give me regular feedback and vice versa so I know how I’m progressing. It helps to talk it out or show the written steps of what you do if you feel like you’re doing a lot but not sure how to manage it.
