I was wondering if there are any other students here who entered into calculus with a bad knowledge of topics such as logarithms and trigonometry. I took pre-calculus twice to try learn these subjects but we never got there both times

(bad teachers in both occasions). I was wondering if anyone has had this experience and what they did to overcome this problem. I am now in calculus 2 and did fairly well in calculus one by avoiding transcendental functions however, I can't avoid them forever and it seems that self study into these topics is tedious and extremely time consuming for me if I'm not in a class to learn the big picture of these concepts. What makes it difficult is that at the same time that I am trying to master these ideas I am in a calculus 2 class and 2 other classes and also have a job to worry about. It just seems nearly impossible. I just want some stories of experience and what people have done to overcome similar problems in their quest to learn higher mathematics.
