A holter monitor is a portable EKG that monitors the electrical activity of a person's heart, generally for one to two days, 24 hours a day. It is most often used when the doctor suspects an abnormal heart rhythm or ischemia (not enough blood flow to the heart muscle).
You can get a computer science degree and after four years you're $100,000 in debt and you still don't know everything you need to code, says Jordyn Lee, a rep for SkilledUp, a self-styled curator of online and alternative education sources.
Take as much math as possible. A computer science degree requires 22 hours of math, starting with calculus. If at all possible, take a calculus course in high school. Take any computer science courses that emphasize structured programming in high-level languages, or take the Advanced Placement course, if available. Take physics and chemistry. Do well in English. As a student in computer science, you will be required to have the equivalent of 6 credit hours of freshman writing courses, 6 hours of Writing Intensive courses, and a public speaking course.
