My most difficult challenge in academics was calculus. Despite devoting multiple hours trying to grasp concepts such as limits, derivatives, and integrals, I still felt exhausted because of the subject’s abstract nature. By the time I decided to get assistance, I was not looking for some kind of shortcut. I wanted to find a way to restore my focus back to things I was good at. https://www.zupyak.com/p/4490003/t/when-calculus-beats-me-why-i-decided-to-pay-for-help
