Looking For A Math Tutor In Beaverton.

Im new to all this but my 15-year-old, freshman, son needs major help in math. Hes at like a 4th grade math level and doesnt understand anything in class. His teacher isnt the nicest and doesnt understand why my son isnt learning. I blame a lot of it on the pandemic as those were prime years of learning the basics. Even though everyone in his family knows math nobody can help them due to the way they are teaching it in school nowadays.. we all know it's important to get passing grades in high school and I just wanna have him set up for success.
