Step 5 in Devising Your Plan: Remaining Flexible
Once you've devised a plan, it's important you review it to make sure it will meet all graduation requirements. It's also important that you remain flexible: your plans, interests, and goals will change while you're at the university. It's normal and natural and good that while you're a student you'll become fascinated with ideas and possibilities you'd never imagined before, and it's important you allow your plans to change as that happens. (That said, it becomes more difficult to change your major the further along you are in your education. So explore majors early, and with intention.) You may not get into a class in the quarter in which you had it in your plan, and that will require you to make adjustments. The important thing to remember is that this is not a plan that's set in stone -- it's a structure that allows you to consider how your time at UCSC will best support you in becoming the person you want to be.
Review your plan regularly to ensure you're on track, and talk with advisors if you have questions.
