<p>So i am thinking of either majoring in pre-med or computer science. I really want to go to UCLA but undecided in major. Will i have time to choose between these two major if I get into UCLA?</p>
<p>Pre-med is not a major. You can major in essentially anything, including computer science, and do pre med. Pre-med is an advisory program designed to advise you on what you need to do to apply to med school, There are a number of math, science, and writing courses that you need to complete in college to be able to apply to med school regardless of whether they are needed for your major.</p>
