It was probably the teaching method. I had an easy time understanding Physics and Trigonometry class but during Algebra it's hard to digest and understand. Then I got older and found that there's a lot of teaching methods and if the teacher is good at adapting the lesson to the students lots of students will understand. Sadly most teachers are not flexible, it's just too hard for them to accommodate all students teaching needs.
