I work with an engineer who went to a rural HS that did not have any math beyond Algebra 1. No Chem or Physics, either. It was a lot more effort for him than for students from better school districts but he got it done. He’s a very good engineer and, growing up on a farm, has the best work ethic in the company.
Is he doing OK in Algebra 2? My daughter tutors Calc and sees that the ones struggling the most do not have a complete understanding of the concepts of algebra. Every engineering course will have the same issue requiring algebra fluency.
