 
 First off, sit down with your academic advisor right away to map out exactly which prerequisites you're missing and how they fit into your new major's timeline. They can help you figure out if any courses can be taken concurrently or if there's flexibility like summer sessions to catch up without overloading. Make a list of the key topics you need to cover, prioritizing the ones that build on each other. For example, if you're switching to computer science and missed an intro programming class, focus on learning basic Python syntax through free resources like Codecademy before diving deeper.
Once you have that plan, carve out dedicated study blocks in your schedule that work around your part-time job, maybe two hours every evening after work. Use techniques like the Pomodoro method to stay focused - study for 25 minutes straight, then take a five-minute break to avoid burnout. Join study groups or hit up professor office hours for clarification on tough concepts, and supplement with online videos from Khan Academy if textbooks aren't cutting it. Track your progress weekly by quizzing yourself on the material to ensure you're actually retaining it. Remember to keep an eye on your overall workload and GPA by dropping non-essential electives if needed, and don't hesitate to seek tutoring services if something's really stumping you. It's okay to aim for steady progress rather than perfection - many people switch majors and come out fine. If things feel overwhelming, talk to a counselor about time management workshops at your school.
