middle and high school math and Computer science courses, SAT/ACT MATH

I have a masters in mechanical engineer and a masters in computer science from USA.
Have worked in the software industry for 10 years and left job to take care of kids. While moving to various countries due to husbands work , could not find reliable schools and tutors. started tutoring kids from both american and British curricula (7 years experience tutoring) and love teaching and more than that inspiring kids to let go of the fear in MATH as it is the basis for many STEM related high paying jobs.
