Top Tips to Pass
Read the Highway Code
Every question is based on it. Read it cover-to-cover at least once.
Practice daily
Short, regular sessions are better than cramming. Aim for 20–30 mins a day.
Review wrong answers
Don't skip past mistakes — understand why the correct answer is right.
Train hazard perception
Watch DVSA sample clips. Click early but not randomly — early clicks score more.
Target 90%+ in practice
If you score 90% consistently here, you have a strong buffer on test day.
Book when ready
Don't book too early. Book when you're scoring above the pass mark consistently.
