When preparing for the exam of subject 2, you should master all the items and register after you are familiar with them. There are no reference objects and reference points in the examination room, so you can only rely on your usual practice and proficiency in items.
How to find a reference for the subject 2 exam?
Compare the positions of the reference object and the objects inside and outside the vehicle. In the second exam, except for the stop and start of the third ramp, other exam items don't need reference objects, while the reference object of the third exam is very obvious, provided by the examination venue, and there is no need to find a separate reference object for comparison.
Subject 2 failed once on the day of the exam. Can I take the exam again?
You can take the exam again. There are two exam opportunities on the day of the second interview. If you fail the exam the first time, you can take it again. The second exam begins with the first exam. Don't move the vehicle without permission if you fail the first exam. Be sure to give it to the driving school staff.
