Do you have desire in your heart to change professions or take a class or start a business? Is point of stopping is that divide is TOO significant for you, stop for a minute.
My daughter Katherine is in 4th Grade at Mount Vernon Magnet School for Performing Arts. This past semester she made Principal's List: she received highest scholastic level possible. One of remarkable bits of information I picked up this year as I have assisted with her homework is that within her lessons in Math, there are already bits of Algebra sprinkled into lessons.
When I was in school, we were "all of a sudden" introduced to Algebra in 8th or 9th grade.
We went from no algebra to all algebra.
In Katherine's case, she is becoming comfortable with algebra now so when she comes to point of taking an algebra class, divide will be quite narrow.
She never looks to me and laments, "But Mommy, I do not know calculus yet!!" It never crosses her mind.
If she ever did, I would tell her reason she does not know calculus yet is because she has neither skill set or abilities TODAY, though in time she most certainly will. I can further encourage her by reporting that even I do not know Calculus, although one of my goals is to take and succeed in this course of study even twenty years post College Graduation.
