I've searched for the developer of Auto Mechanic Courses, but there is nothing available. The developer is listed as being OS Project Software, and I've used this string to look up its website, only to find out that it doesn't exist anymore which means it's impossible to provide the required resources.
This means, you will have to look for something else regarding Auto Mechanic Courses, but as word of advice, try looking in your area for government recommended papers. They also have software and courses available to buy.
