I am preparing for Thailand. There is a sentence where I want to say that I have noted down all the necessay information and contact numbers.

So can I say. I already wrote the information.

I am not sure I we can use "I already wrote". I feel it should be, "I have already written" or "I had already written".

Please assist.




It's I've already written.

Thanks Johnny. How can I explain the mistake and how can I convince that "I have already written is correct"?
You can convince because there are grammar rules. One rule is that had doesn't go with written. You can explain the mistake in the same way you convince it.
I've already written, because had doesn't go with written.
