The vehicle mechanic bundle course is really poor. The contents are too American for UK customers, spelling mistakes, dead link to supporting video material, and even one of the exam questions has a word wrong in it. It was really too simple in content, and provides some advice which applied to modern vehicles would be damaging and dangerous - i.e. coolant mixture should be 50:50 with distilled water - most modern car systems use ethylene glycol with an organic additive in them. Add water to these systems you will wreck them. The truck module duplicates much of the previous material just in different words and is very non-UK in terminology. This course comes from a British provider, so why spell Tyres, "tires". seems really lazy and poor standards to me. sorry, disappointed.
