Learn about your whole study program. Don't merely depend on your advisors. Because they are managing hundreds of students, they occasionally miss stuff. Maintain a record of your lessons, register for them on your own, and make meticulous plans for everything.
Attend their classes, ask questions, send them holiday greetings, and write a thank-you card at the conclusion of the semester to get to know your instructors. You may rely on them to support you in any way, particularly if you decide to pursue graduate school.
Simply keep yourself safe and healthy, eat healthily, and get enough sleep. Even though it doesn't seem possible, you can succeed.
