If I passed algebra prep in 8th grade.will that count forwards my diploma
Need a little more context. Are you talking about your HS diploma? Are you in HS or still in Middle school? What level of Math are you at currently?
My guess is that “Algebra prep” is pre-algebra. While you’ll need to speak to someone in guidance, it would NOT count as an Algebra credit in my school.
Generally you need four years of math AFTER graduating from 8th grade. Talk to your high school’s guidance department for advice specific to your school.
In DDs high school, there is a “Preparation for Algebra” class taken the summer before 9th Grade that will give you half a credit as a math elective, but not count as a core math requirement.
if it is pre algebra that is a pretty common level for middle school. I’ve haven’t heard of high schools giving credit for middle school math below algebra 1 level. Also not all schools give credit for math taken before high school no matter what the level so you would need to talk to your own school for that info.
