Keep studying. It's good that you're confident, but the exam is going to be harder than you think.

Minor in computer science if possible, if not learn yourself a programming language. It's something a lot of employers are going to look for, and the knowledge you gain from it will help immensely at any job you find yourself in.

Speaking of jobs, when it comes to getting one, experience is key. A student with 1 exam and 1 semester of intern experience will get a job over a student with 2 exams. If you are unable to get a internship, DO NOT take more than 2 exams while you're in school. Companies do not want someone who has lots of exams and no experience because:
1. You cost too much.
2. It leads them to believe you lack social skills.

Social skills, what about them? The actuarial field has become extremely competitive in the last few years, you will be competing with lots of other people for jobs. These people will also have passed exams, you need something that makes you better than them. This is gonna be decided in your interview. There is a certain stigma associated with actuaries (and most of us fit it to some degree, even if it's minor), and an employer is going to use an interview to gauge your personality and see if you're someone they want to work with.
You're gonna want to join whatever actuarial groups your school offers, be it Actuarial Club or Gamma Iota Sigma (the national risk management frat), or something else. Go to the events they offer. You will learn what to say and what not to say on interviews, as well as how to compose yourself. More importantly, you will get a chance to communicate with other people in your industry so that when it comes to an actual interview you can speak and confidently.
