Question

Okay, next time I will. Thank you very much! It is correct grammar?

Answer 1

Another way you could improve your sentence structure is, removing 'It' and placing 'this' after the 'is' - it would then read - 'Is this correct grammar?' another way you could write it would be 'Is this grammatically correct?'

Answer 2

Yes, it seems like your sentence's grammar is perfect. The only problem is after your two sentences. You wrote "It is correct grammar?". This is a statement with a question mark at the end. To fix it, switch "It" and "Is". You'll get "Is it correct grammar?" Hope this helps!
