Good day, I NEED HELP!

I am in the process of creating training modules (to meet OSHA training requirements) in power point and I need to create a series of Multiple Choice tests for each employee to take to verify they have reviewed and understand the material which will need to be saved with the test takers name as part of the file name.

I would like the test to address the following;

1. The employee must be able to enter his/her name (which needs to be the file name),

2. The employee must select an (ultimately the correct) answer from a drop down box (for example) but radio buttons are OK too,

3. Auto grade with immediate feed back so the employee knows if they have answered the question correctly or not (at the end of the test is OK),

4. The ability for the employee to go to any incorrectly answered question and change the answer,

5. Only after correcting ALL answers, the test needs to be saved to a secure folder.

So far I have created the power point presentation(s) with a hyper-link (at the end) to a word doc test (Word 2003) using check boxes and/or radio buttons but don't know how to grade the test.

I've looked at trying to do this in Google Docs but don't think that is a direction I want to go, I'd rather keep it all on site and within MSOffice.

I am considering trying either Excel or inserting tables in Word so I can use math function to grade.

I am a novice and am stumbling along here so any and all suggestions are appreciated.
