If you read my last post, this is something like that.
For the ITGS exam, it's common to worry how much do I have answer. I mean, if you've read the mark scheme of any ITGS exam, it's always ask for the candidate to answer like a lot! And it's kindda scary to think that you may not know how much you must answer.
When you're answering any ITGS exam (I strongly recommend to study the previous years exams), the number of answers that is expected for you to answer is on these -> "[ ]". For example if at the end of the question there's something like this "", then that means that you must provide FOUR answers, and don't worry, in the mark scheme there's usually more possible answers than what it's asked.
Hope it helps,
