Worried about drivers test,driving an unfamiliar vehicle. Advice?

So tomorrow is my long awaited drivers test.Ive been driving my moms micro mini van (2006 Mazda 5) For the past almost 2 years. Ive driven it pretty much every day since i got my permit in 2009, and im very good at driving the car. It's small,simple,and easy to maneuver.Now the problem with these cars is that theyre first generation. So the factory essentially mass produced them without much consideration for the rear suspension. There was a recall on the car but we missed the cut off date. The rear shocks and struts constantly break,and the wheels lean inward. The only fix is a 300 dollar kit on the mazda website. And to add to that, the check engine light and ABS light are lit up on the dash because of a mishap after we took the car to a local car shop. Theyre just bad sensors, but still. We took the car to the DMV to see if i would be able to take it. They denied ONLY because of the lights,even after a note from the shop and a very detailed explanation. So now im being forced to drive my dads 2004 F150 stx.Which im not very use to because he is always working. Ive driven the truck maybe 13 times in the past 2 years. And only short distances. Its hard to drive and i cant ever turn right. Anyone have advice on what to do? I would drive my car for my test,but its uninsured at the moment and not plated. Thanks for any help
