Master your desmos skills for god's sake. Tell me 1 math exam where you have access to graphical calculator. That's ridiculous. But what's more ridiculous is that people OFTEN overlook this enormous possibility.
How to master? Just solve absolutely any problem with desmos, and I mean absolutely any. Try every single one of them, and once you have a thought "how can i do this with desmos?" go to reddit/google/chatgpt and ask them. You're not the only one who encountered that problem, which means that there are other people that already encountered that problem and, possibly, found an answer/solution. The only thing that is left for you is to find it. Found it? Great, now, move on and on and on.
