A new law offers California students several ways to make up for lost learning after the profound disruptions of the pandemic year. Under AB104, signed into law Thursday by Gov. Gavin Newsom, K-12 students have a number of options to make up for the 2020-21 school year. They include retaking a grade level, changing low grades to pass or no pass, or enrolling in a fifth year of high school for juniors or seniors.
