Answer Booklet In P4 Exam

Hi,

I am sitting the P4 exam in March.

I was wondering in the exam do you have to write on both sides of the pages. As in, would I be penalised for writing on the one side of each page (the right-hand page in my case)?

The reason I ask is because in long questions, and with all the working that will have to be referred back to, I have found in past exams that having workings on both sides of the page really slows me down when having to look back at workings.

So my plan was to use a booklet for each question and write on one side of each page.

Is that allowed in an exam or will I be expected to make use of both sides of the page in the answer booklet?

Thanks!
