The NS conductor test contained the following categories:
1) Reading: basically, reading comprehension. It's one thing to simply read words, but another to be able to infer what they mean altogether. There were three reading samples in my booklet with three or four questions per sample.
2) Mechanical: basically, mathematics (shop arithmetic, pre-algebra, & algebra) & mechanical reasoning. Math examples in my booklet included: multiplying & dividing decimals, adding & subtracting fractions (e.g., halves, quarters, eighths, & sixteenths found on a basic ruler), & two-step equations (no inequalities). Mechanical reasoning examples in my booklet included levers, pivots, & gears.
3) Facts: basically, verbal & deductive reasoning. A sample contains five to seven facts (in bulleted sentence format) and three to five questions per sample. My booklet contained three of these.
4) Personality/Behavioral Assessment: self-explanatory. Topics covered in my booklet: safety, interrelationships, & multitasking. This category was by far the biggest with safety the biggest topic.
