At the same time, the striking blow from the hammer forces the impact driver down into the screw reducing or eliminating cam out. This attribute is beneficial for Phillips screws which are prone to cam out. It is also excellent for use with the Robertson square socket head screws that are in common use in Canada.
PSAT scores are reported on a scale that runs from 20 to 80, 20 being the lowest and 80 the highest. This is a parallel to the SAT, which scores between 200 and 800 on each test part. If you want an idea of how youâll do on an SAT test, simply add a 0 to your score.
The new SAT, on the other hand, will have a range of 200 to 800 for each section and a range of 400 to 1600 for your composite score. Your PSAT scores help predict your SAT scores, but the scale is shifted slightly lower to account for the fact that the PSAT is an easier test than the SAT. A perfect PSAT score, for instance, doesn't equate exactly to a perfect SAT score, but it does indicate that you're likely to score very highly. The new PSAT and new SAT share another similarity with their adoption of rights-only scoring.
