-- submitted answer -- I was never very good at maths when I studied at school. Maths and geometry were a huge challenge for me. The subjects included in mandatory exams. I found it quite difficult because the main idea of math is connecting topics. If  I missed one lesson, I couldn't make excesses. Exsesases bild on previous tapes. I had trouble visiting the school for 5 years because I travelled a lot with my basketball team to competitions. Maths’s teacher told me went out of school after 9 grade. In her opinion, it was not realistic to pass an exam after 11 grade for me. The exam was strict because it was one time when the education system worked with it. There were 5 observers and a closed package with exercise. Non loopholes for cheating or using a calculator or clause. I got very annoyed by the speech from the teacher. I did not know how to make it possible for me, but I continued my school education still 2 years. Three months before the exam I understood that math excesses are typical, and if I had a roll model key I managed it. I decided to learn the construction of the maths exam with a private tutor and went to the class three times per week. Eventually, I managed it. For three months i have broken up with it. My result was higher than i expected. I got a certificate, for me, it was quite an achievement. -- suggested correction -- I was never very good at maths when I studied at school.

Typical mistakes This - an example of sth = Russian This is an example of sth = English Explanation of Corrections by ChatGPT: "Maths" is commonly used in British English, while "math" is used in American English. To maintain consistency, choose one version. Here, I've used "math." "The subjects included in mandatory exams." needs a subject and verb: "These subjects were included in mandatory exams." "Exsesases bild on previous tapes." should be "Exercises build on previous topics." "I had trouble visiting the school for 5 years" should be "I had trouble attending school for 5 years." "Visiting" implies going occasionally, while "attending" implies regular presence. "Travelled" is correct in British English, while "traveled" is the American English spelling. Consistency matters. "Maths’s teacher told me went out of school after 9 grade." should be "My math teacher told me to leave school after 9th grade." "In her opinion, it was not realistic to pass an exam after 11 grade for me." should be "In her opinion, it was not realistic for me to pass an exam after 11th grade." "The exam was strict because it was one time when the education system worked with it." is unclear. It should be "The exam was strict because it was the only time when the education system worked with it." "Non loopholes for cheating or using a calculator or clause." should be "There were no loopholes for cheating or using a calculator or notes." "Clause" is not relevant here. "I did not know how to make it possible for me" should be "I did not know how it would be possible for me." "Still 2 years" should be "for 2 more years." "Three months before the exam I understood that math excesses are typical, and if I had a roll model key I managed it." should be "Three months before the exam, I understood that math exercises are typical, and if I had a role model key, I could manage them." "Went to the class" should be "went to class." The article "the" is unnecessary here. "For three months i have broken up with it." should be "For three months, I worked hard at it." "My result was higher than i expected." should be "My result was higher than I expected." Capitalize "I." "I got a certificate, for me, it was quite an achievement." is correct but can be clearer with punctuation: "I got a certificate, and for me, it was quite an achievement."
