Quality > Quantity. You are solving too many easy problems. Almost half of your solved problems here are of difficulty 800 and I don't think you learn much from them. Instead, you should pick problems that are somewhere above your rating, I think 1000 would be optimal. If you are able to solve most of these problems within an hour, aim even higher. If not, read editorials and keep practicing. You can learn a lot from problems you can't solve.

As others said, keep solving problems below 1000 is kind of meaningless. Try 1000.

What's more, I think you should think independently for at least 20min before checking the tutorial.

Good Luck.
