Have you tried watching math YouTube? I find that the key to learning math well is to be genuinely interested in it. If you find a good math communicator to watch/read, it helps to motivate your learning and make it easier to get through the parts that are (even if you end up loving math) just boring.

Also, if there’s a past math class you’ve taken and passed but didn’t feel you really got it, try to find a way to get those ideas to sink in. Math builds on itself. If you don’t have the foundations, you will struggle with what comes later.
