「We currently have 2 6th graders skipping 6th grade math this year and taking 7A instead. 第2子 is one of the two. This is the first year, in the time that I have been at 中学校, that we have offered a placement test to skip 6th grade math. 

With successful completion of 7A in 6th grade, students would go onto Algebra 1 in 7th grade. This is a high school level course that carries a high school credit. So 第2子 could earn her first high school credit with an average of 70 or higher. 

Then in 8th grade, 第2子 would be taking Geometry, which is not currently offered at the middle school level. The details of how this class will be delivered to middle students has not been determined yet, however, in years prior, students at市内の他校Middle School would drive to 高校 to take Geometry there and would then drive back to 市内の他校 to finish their school day.

With successful completion of Geometry, as a 9th grader, 第2子 would take Algebra II.
