Hello, 

Its mentioned in the exam rules that we cannot use any highlighter or any other colour ink to make the headings attractive and all, but can we use a pencil to underline the headings and subheadings? and can we use black and blue pens in exam together? i mean, like black for headings and blue for the matter in it?
