judging from the photos you provided, your handwriting is neat and clear. And there are few traces of using an eraser in the photos of your math homework, which is commendable-and I appreciate it most! Explain that you are a good student who is good at thinking and studying hard!
Of course, your handwriting is immature and has not been systematically studied. Fortunately, you have realized this, so it doesn't matter! Next, go to the bookstore or online to find your favorite copybook, and practice more in your spare time. Of course, it will be better if you can visit a master nearby.
The above is my real opinion after reading your homework. I hope it will help you a little.
good luck
progress and happiness!
