We compare the same vehicle category and reporting period at the same CBR exam centre. Only first exams at this centre count, not the school total. The school's busiest centre is selected initially. The comparison score weights CBR results at 70% and the whole-school Google rating at 30%. For CBR we use the 95% Wilson lower bound, which accounts for exam volume. A lower bound of 30% gives 0 component points and 70% gives 100, with a linear scale between them. This is not the ordinary pass percentage. Google uses 20 reviews at 4.05 as a neutral prior, reducing the influence of small samples. An adjusted Google rating of 3.2 gives 0 component points and 4.9 gives 100, with a linear scale between them. Each component is capped outside these thresholds. A score requires at least 10 first exams at this centre and 5 Google reviews. The Wilson lower bound already discounts small samples, so a smaller school enters without an advantage. A rank requires 5 comparable schools; ties share a position. These thresholds are editorial choices, not measured population limits. Ranking uses the unrounded score; rounded scores can appear tied. Prices are excluded. This is our editorial comparison, not a CBR endorsement or a prediction of your pass probability.
