In both road and rail vehicles, the wheelbase is the distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is defined as the distance between the steering (front) axle and the centerpoint of the driving axle group.
ACT Scoring and Superscoring. First, letâs quickly review how the ACT is scored. Each section is given a scaled score between 1 and 36. Then these area scores are averaged into your composite score, which also ranges between 1 and 36.
The ACT score used in these calculations is the âCombined Highest Composite Score.â In other words, you donât even need to score a composite of 31 on one actual ACT test, you can use your best scores across sections of multiple tests.
