Help please

Those lines are generally just for the examiner to write comments about what you've written for the examiners reports on those exams. I don't think they will mark you down and they definitely won't if it didn't tell you not to write outside the lines.

Hi thank you for replying! Do you know if the barcodes are located in the top or bottom of the paper?

I don't know where they are for business exams but they seem to be at the top most of the time

They look like this right?

Yes
