if someone can check the assembly origin because I am having close answers but with different signage.
If you check your Origin - note that you have constrained your part backwards.
You can reset the origin. Edit: I see that you have created a Coordinate System, but you did not set the X and Z directions correctly compared to the test image.
But when taking a test like this - you should note the position right from the beginning and model accordingly - that way you do not lose any time.
