It is important though that one must seek a Calculus tutor for his Precalculus help on relations and functions, systems of equations and inequalities, polynomial and rational functions, exponential and logarithmic functions, trigonometric functions, polar coordinates and complex numbers, conic sections, and sequences and series.
Precalculus and Calculus subjects are available only in some private high schools in the Philippines. During my time, it was only in College that I had it and as I mentioned, I did not enjoy it as much as others enjoyed the subject. Today, the internet even offers Calculus help, Precalculus help and even Statistics help free. You just have to pick the best tutor there is.
