It goes without saying if you get to your test in good time then it’s a good start.
Being late for test and you’ll miss the whole test itself and rushing to get there last minute will make you tired and nervous.
Test centres like Goodmayes in East London advice you to be there no more than 10 minutes before your test. Leaving enough time to relax yet not too early to clog the car park.
Talk to your instructor about how you feel about the upcoming test. Just make sure you get enough sleep and lot of rest the night before your driving test. Dont be stressed about it, talk to your instructor about it if you’re feeling too stress and nervous.
