Meaning of 'AB' in school?

I've noticed the abbreviation 'AB' in my school schedule but I'm not sure what it means. Is it something related to class schedules or performance?

The abbreviation 'AB' in a school schedule typically refers to "A Day" and "B Day" block scheduling. In this system, schools alternate between two different schedules on different days, usually to accommodate a greater number of classes, longer class periods, or special activities. Instead of having all of your classes every day, you would have half of your classes on 'A Day' and the other half on 'B Day.' This type of scheduling helps give students and teachers more time to delve deeper into course material.

For example, on 'A Day' you might have Math, Science, English, and Art, while on 'B Day' you have History, P.E., a Foreign Language, and Music. Schools can follow different patterns with block scheduling, such as A-B-A-B or A-A-B-B, depending on chosen school calendar.

It's important to familiarize yourself with your school's specific schedule so you know which classes to attend on each day. You can check with your school administrator, counselor, or teacher for clarification on how your school uses AB scheduling and any related expectations.
