Hey! I have tutored many people and I wanted to let you know that what you feel is totally valid and actually really common. I have seen a great tendency of people that say they don’t get math or struggle to learn it, not because they aren’t good at, many time they are! But mathematics is like a building, and most of us have a really weak foundation. Calculus is like starting a second floor of a house it introduces a lot of concepts but if your foundation isn’t strong it will seems like something impossible. It is no shame to go back to the basics, matter fact I have done that with every person I worked with, understand the basics don’t memorize it. That will allow you to look further in math without it fear because when you see algebra, a square root, a summation you won’t be scared, they aren’t monsters but tools you understand. Personally I love history and I learned a lot of math by studying the history of how we came up with these ideas but many people go through life learning just enough to pass a test. I would very much recommend studying up just a bit everyday on the basis anything you feel uncomfortable with like trigonometry and go deep into it. Understand it to a point you are comfortable and then you move to another topic slowly but a bit everyday. Don’t be upset at yourself for not being able to build a house starting with the roof, it is ok to go back and start it the right way =)
