помогите исправить ошибки, английский язык !!!если они есть

I study in the seventh form. I study English at secondary school. I have learnt English about 6 years. Earlier English presented a problem for me, but when I started learning everything, English became much easier. Learning English often helps me to talk in the world chat (only English is spoken there). When I have some problems, I use a dictionary. But mainly I have problems with the grammatical rules. Sometimes I mix some of them because I am inattentive.

I study in the seventh form. I study English at secondary school. I have been learning English for about 6 years. Earlier I used to study English hard, but when I started learning everything, English became much easier. Learning English often helps me to talk in the world chat (there I can talk only in English, read texts in English, and listen some music.)When I have problems I use the dictionary. But in the main I have a problem with the study of grammar rules. Sometimes I get mixed some of them because I am inattentive

Я седьмая форма. ?

Английский давал мне трудно, --что он давал? возможно трудные времена

Но в общем у меня проблема с учобой граматических правил. --можно просто проблема с граматичеких правил без учобой

Некоторые из них, я путаю их потому-что я невнимательно. --них их 2 раза повторяется одно за другим некоректно. В конце перед словом невнимательно нужна приставка и вместо слова невнимательно можно использовать слово не концентрирована.

Успехов
