Хуже всего у меня обстояли дела с химией (weakest subject). Я учил наизусть формул и задачи, но ничего не могло улучшить (improve) мои знания. “Пора (it’s time) те делать что-то с этим предметом,” - говорил мой учитель. Перед последним экзамен я постарался. Я получил “5”, но далее следовало краткое пояснение: “3” - за аккуратность, остальное за знания.

"Pora (it's time) are doing something with the subject," my teacher said. Before the last exam I tried. I got a "5", but should have a brief explanation: "3" for orderly, the rest for knowledge.
