Well, I always make mistakes about grammar.
Sometimes understand the rule is being hard, so I choosed to grammar exercises.
These exercises are really helpful for me.
I was always doing the same mistakes and I understood what is their right using.
I selected articles and prepositions od direction exercises.
Because when I send my essay to smarthinking my feedback is always including these mistakes.
However, my result was good only 3 or 4 were wrong.
I need to focus on the using of ''the''.
The usage area of this article is too large so, sometimes I have diffuculty to understand.
I hope I will solve my problem to practice more.
