In fact, as long as you study hard, nothing can be learned badly. What you lack now is confidence. You might as well find some simple questions to practice by yourself, but they are simple for yourself, not those experts. Doing so will not only help to lay a solid foundation, but also cultivate your self-confidence. Do simple questions for a while first, and then gradually deepen the difficulty. In fact, when you overcome a difficult problem, only you can feel a sense of accomplishment and excitement. A correct attitude is the best teacher to like mathematics rather than hate it.
