Just relax, have fun driving, and just think of it as a normal driving lesson. I failed twice: 1st - hesitated at the roundabout, to the point where the driver instructor had to shout at me to move eeek, 2nd - my steering, almost hit a car when I pulled out.
I've heard they haven't asked much about the bonnet, because of covid, but I won't risk not learning just in case.
