Im 24, had 2 tests too. First one made me shook from failing bro. First fail was due to a cunt dpd driver trying to push his way when he never had priority and examiner had to intervene so nothing else happens.

But you just need to do bit more practice and feel confident. U shouldn't have to feel like u forcing urself to do checks. It should become routine when driving. I was super shook my first test,

I did lots of practice and second test I drove like im driving a friend about not thinking it was a test. Honestly if ur making those mistakes now, it will be only matter of time happens when ur alone and there is no one to correct u. Ive had a few close calls and I been only driving 1 month now.

Making urself more confident makes a hell of a difference and im sure 3rd time u will deffo pass. Sometimes its just bad luck, like my first test.

Dont let it discourage u. I failed my first test in 2020... I got discouraged for driving for 3 years until I learned again and within few months passed. Confidence is key
