I agree, use the 3.70 materials you have.
I logic and principle will still be the same.
Just make sure you read the scenarios used in the example companies:
Ex: Video store wants to create an invoice… What would you recommend…
Even though the names will change or process, still the logic will need to follow.
Your company (Nameless) should invest on internal training materials. This is my personal 2 cents.
The most powerful tool any company has is the investment it has in the staff it keeps educating. The company is reap the benefits making you and the company look good when you aquire the skills.
If they don’t pay for the exam. Let them pay for the time you need to invest in the office.
Remember the old saying: penny wise, pound foolish. (I don’t care what part of the world your at, the company that is penny wise and pound foolish, sooner or later will lose an account and a gifted employee. So study hard and pass, you will be richer in many ways.
After all, they are going to benefit with you and your license!
