Just screw it up, take it easy.
I taught + did not worry = passed
I didn’t teach + did not worry = (they probably showed and told something at school in the classroom) I remembered and passed it.
Breathe in. Exhale. So 10 times and quite consciously, focusing on the very process of breathing. Now look.
The sacralization of the USE as the final exam of the entire life of a 16-17 year old person makes it almost impossible to adequately perceive the exam. But in fact, firstly, no exam defines you as a person. The main question that the Unified State Exam answers is how you managed to organize preparation for the exams, and not at all "am I smart enough for higher education." Fighting and defeating anxiety is the last and most important step in this entire long preparation. Think of it as the last meters of the marathon, where it is more important not only to sprint the remnants of information, but also to breathe deeply so as not to become a victim of asphyxiation.
Secondly, the losses from the failed USE with an adequate approach, a healthy psyche and lack of pressure from relatives is minimal. You will just prepare for a year more and it's not a big deal. I would generally recommend that some high school students think about the gap year before choosing a university. This is life, not a high-performance sport, so it's not the points themselves that matter to you, but how you use them. And this task is sometimes more difficult and trickier than preparing for an exam. Maybe you will understand something about yourself this year. The entire educational scheme and structure of the school system, funding of which is tied to student scores, deliberately (?) Creates the illusion that the Unified State Exam is the top of a mountain. Local Everest, after which there is nothing. This is not the case. The exam is just a start. Further it will be more difficult and more terrible. Other events in life cannot be "retaken". And here - only a year. Believe me, a badly written USE is not the worst thing in life.
In my tutoring practice there was a story about a very bright girl who did not pass something there and, having 100 points in one of the core subjects, did not pass to the journalism department. Now she is preparing to enter a European university to become a neuroscientist - less than a year was enough to understand the futility of the life of Russian journalism. And this is an example of how, with the right approach, any event can be beneficial.
Do not drive into your head any rubbish like "Your whole life depends on this exam," or "If you fill it up, you go to vocational school." Believe me, the exam is just a regular test, no need to worry. I would also advise you not to learn anything the day before the exam, it still won't help, and go to bed at about 21:00 to get a good night's sleep.
Don't worry. Look here. I passed last year, but lost my head because of the excitement, and scored little points. Therefore, do not worry. Everything will be fine. The main thing is to believe in yourself. Good luck
