Hello guys!

I am 17-year-old girl.

These days, I have some problems.

 About 3 weeks ago, my boy friend started studying English.

Actually, he had withdrawned high school, and he had never studied English.

Therefore, he finished phonics about 2 weeks ago.

 And now, he wants to study about English grammar.

So, I need your advices!!

Which book is better for him?

And if you don't mind, could you recommend another grammar work books for me?

Well, I also have never studied about English grammar with any work books.

For more specific, my 모의고사 level is 2.

(Is this sentence right grammatically?)

Therefore, I hope you guys give me some recommends for my boy friend and, me!

Thank you for your kindness, and have a great day every one :)

(And if there are grammatically wrong sentence, please give me some teach!)
