That is correct 
- Should the third equation in number 9 be 500 rather than 5000? --Molniya 05:38, 19 April 2008 (UTC)
- That is spot-on, I have corrected it, thanx! for your interest in this course. -Thuvack 05:32, 21 April 2008 (UTC)
Btw, number 8 is wrong.
Aptitude, or Final Exam? 
I really admire the work you've put into this. It shows off your skills with wiki markup. I have to ask, though, if this is really an aptitude test. It looks more like a final exam for those who have already completed the coursework. TWFred 19:43, 18 April 2008 (UTC)
- Thanx For the comment! I view it as an Entrance test, for those interested in Engineering field, The coursework should/will be at a High School or Secondary Level. As Wikiversity Develops I am hoping to contribute to setting up that portion( If it does not exist as yet) I know That There is a primary Education Portal. All-in-all This is aimed at being a body of entrance tests for Electrical Engineering.Please refer to Course wish list for a preview of where this course is headed. -Thuvack 05:27, 21 April 2008 (UTC)
For number 8, the only local maximum is at (6-sqrt(12))/12, with value sqrt(3)/18
For number 10, the maximum profit of P = 200x + 5000y is not at (150,150), it is at (0,250).
I have changed the answer for both of these to "None of the above."
