6 weeks until practical test

hey so i have 6 weeks until my test.. i keep making so many mistakes in my lessons and i cant seem to get better.. i always come out of my lessons feeling like i wont be ready for my test and that i will fail miserably.

last two lessons i have had i have taken turnings too wide or too fast. gone when i shouldn't have, hesitated loads. stalled and not handled it well in middle of roundabouts !! missed speed limits signs and almost missed a mini roundabout.

its honestly a shit show at the moment.. i thought i was ready and now it just feels like i'm no where near.

idk what to do and how to avoid these on test and just in general.
