I believe I obtained a 41, and was shocked myself, yet I did not fret over it.
People learn a different rates and by different styles, so focus on what you can only control; yourself. Keep your eye one the ball.
Work on the course and take many practice exams, those are the key. Typically, if you can get around 80% on the simulations, you would be prepared for the test.
I know of many folks that did terrible on practice tests and still passed though.
Focus on you.
