Up until the COVID-19 pandemic the school had a semester model with the school day start at 8:40 am and end at 2:48 pm, with 4 periods for classes. 6 minuets was given in-between periods, 45 minutes was given for lunch, in-between periods 2 and 3, and periods 1 and 2 as well as periods 3 and 4 switched with each other every single week. Since the pandemic the school has adopted a quadmester model. The school day lasts from 10 am to 4 pm with two periods, four blocks, two blocks for each period, and 1 hour of lunch in-between the two periods. In February 2022 the school has returned to the semester model with 4 periods for classes, the 6 minutes between classes and the 45 minute lunch was reinstated.
