Online calculator
In the mock test from mba.com, once I switch on the online calculator, I cannot go back to the original question screen unless I turn the calculator off, thereby losing valuable calculations. Is it the same for the actual exam too?
This would be the same on the actual GMAT as well. My suggestion is to make a note of it in your GMAT scratchpad!
Plus you are looking at the IR section – so don’t worry too much! 🙂
