1) Start the HW assignments as soon as they are assigned. I've always done this and have noticed a lot of students push assignments off to the last minute which is a terrible idea. If something goes wrong or you underestimate the time something will take, its almost always too late to correct it. Also imagine the professor being overloaded with emails from the people who waited last minute, odds are your not going to get a response

2) Read the chapters in the books early. This helped me because I would always be a week "ahead" and would already have an idea on the topic being introduced so that way the lectured would be for clarification on things I didnt understand while reading the chapter. This helpful because instead of being introduced to a topic in lecture and then needing clarification afterwards, the book doesnt always help and sometimes it may make you more confused. So using the professor for clarification before any HW is assigned is definitely the way to go.

3) Create a schedule and stick to it! I dedicated Monday through Friday for doing HW/working on group projects and Saturday and Sunday for reading new chapters. Now it doesnt always work out perfectly, some weekdays I read chapters for classes that I finished HW for or didnt have any HW in and on some weekends I did HW for classes that I couldnt complete during the week (typically because of group projects) and then read the chapters. However, I also dont work a typical job, I do food delivery like Uber eats and Door Dash so I can clock on and off when I want to so that gave a lot of flexibility.

4) If you have group projects, try to pick a group who you know has members that are responsible and have a similar mindset of having time management. There is absolutely nothing worse than being in a group and members push things off till last minute
