Conditional

I learnt 'comditional' today.

I totally lost in the middle of class.

Then I did some homework at home, I think I understood now.

But I don't think I can use it a lot.

My class mate said they use 'conditional' a lot in a writing and conversations.

But... I don't think I used this a lot with mine.

If I have used conditional a lot, my English would have been better than now.
