Hi @sangkhamatr, I assume you're in Engineering?
There isn't an RMIT-wide calculator policy - so I would check with your teaching staff to see if (a) a calculator will be required for your exams, and (b) they require some sort of check on the calculator.
In my Engineering subjects, calculators haven't been required in final exams - it's either relied on algebra or number calculations which are simple enough to manage without a calculator. Your courses might be different though, so please check with the teacher.
RMIT Connect monitors these forums at 10am and 2pm every day, but please call for urgent matters.
