Your degree is what you will get upon graduation. You will actually have a paper diploma. There are a number of different types of degrees - associates degree (a 2-year degree), bachelors degree (4-year degree) and various postgraduate degrees like your masters degree or your Ph.D.
You will achieve your degree in your major field of study. For example, if you graduate from a university in which you majored in Psychology, you will have a bachelor's degree in Psychology. If you don't know what your major is, you're likely an "undeclared" major. That simply means you haven't decided what you want to major in, yet.
in my opinion A typical argumentative essay comprises three or more paragraphs that explain the reasons why you support your thesis. Each body paragraph should cover a different idea or piece of evidence and contain a topic sentence that clearly and concisely explains why the reader should agree with your position.
