An ASU class schedule is more than just a list of times; it is a structured database that tells you exactly which room you need to be in and who is leading the instruction. You will encounter 'Course Prefixes' (like ENG or PSY) and 'Course Numbers' (like 101), which together identify the specific subject and level of the study.
Beyond the basic identifiers, you must pay attention to the 'Section Number.' Since many popular classes are taught by multiple professors at different times, the section number ensures you are looking at the specific instance of the course you actually registered for, preventing the common mistake of showing up to the wrong lecture.
