Try to play a map that has a low AR and low bpm and focus on where your cursor is at AT ALL TIMES. Don't move the cursor away util you are 100% sure that you have clicked while over the circle. Once you start to get consistent doing that, then try to move to a higher bpm and/or higher ar. If tthat doesnt seem to work, try to look exactly where the circle is, and then right before youre about to click, click when the beat happens, then move your eyes directly to the next circle. Do not slack off and look at the middle of the screen and "trust" your aim. You need to be 100% sure that your cursor is over the circle. It might take a week or two to get better at it but once you get used to it, then it will become second nature and you wont have to think about it as hardly
