Remember, MSM: Mirror signal maneuver.
Make it really exaggerated that your looking in your mirrors and blind spot. Just exaggerate anything that makes you look like a safe driver.
Take your time when doing your maneuvers. If you have to do a reversing one, just use your clutch, no gas, unless your going back up a hill. And really practice them, and always check your blind spot before you set off. Don't drive at the speed limit, stay about 5 MPH below it, so you've got a bit more time to change lanes, some wiggle room to speed up and slow down for hills, and to adjust to situations.
Ask your instructor if you can go for a drive around prospective test routes before your test, and get to know the area around the test center.
