talk to upperclassmen in your program and make friends in your major. depending on your program, classes could be more engineering-heavy or math-heavy (or both). i think it's most important to not get intimidated if you lack experience and stay interested, patient, and willing to learn/ask questions. if you can, look at languages your intro classes are taught in and try learning the syntax. there are a lot of online resources nowadays (videos, tutorials, etc). once you pick up some basic syntax, you can try beginner-friendly practice websites like codingbat or codesignal's arcade section to improve your grasp of a language and try doing some small projects you like as well. best of luck!!

they are the cheap marble composition books you can often get for 50 cents or so!
