Do you realize that people who graduate with other types of master's degrees would be lucky to make anywhere near $80K right out of school? An entry level job with a master's degree in accounting + a CPA license starts around $50K. A person with an MBA and no work experience is fortunate to take ANY job, regardless of the pay.
Work on getting A's or B's on all your core science classes. Focus on keeping the option for grad school open, not on what your finances will be like 7-8 years from now.
