1) is it better to read the requirement first and then read through the scenario OR 2) is it better to read the scenario and then read the requirement?
I would have a very quick read through the scenario without going into any detail, then read the requirement and then go back and read the scenario in more detail.
Do watch my free lectures working through a few past questions, where I explain the approach that I would take. (They are linked from ‘Revision Kit Live’ on the main AFM page.)
