Studying&Student burnout

Most teachers here expect you to drop everything you got going on during your exam year. I can understand stopping playing video games, watching movies etc. But they also keep discouraging you, saying that you're apparently "too late" If you have not been studying since 11th grade.
I have been studying as much as I can and trying to keep my hopes up for the most part. I will be posting my progress on here, as a memorial of my exam year. Currently I do not have the time to design my own layout because, god, HTML/CSS or coding in general feels so difficult for me. Last time I watched a guide video It took me 2 and a half hours to set the main background and I am not even going to talk about changing the icons of everything. I also use spacehey.
