On a different note from my other comment here: don’t fall in the traps of letting some “evaluation” define you, or of considering your memory or “ability to think” permanently/unchangeably “poor”. While certainly some parts of our biological makeup may be more or less permanent, both memory and thinking skills are, well, skills that can be improved with training and practice.
Don’t get down on yourself or develop an unhelpful belief or attitude about yourself. You can and will improve with practice, and you are not defined by a test result.
