Appropriate to meet with prof. to discuss low quality exam I am in an MBA program and last week had a two part test for a marketing class. I was under the impression the first part was just analysis, essentially creating models and writing notes on trends so you can quickly and easily answer the questions on the test (take home, given 3 hours to complete during the regularly scheduled class time). 

The first part was much more extensive and actually had 6 questions with 3 sub questions per question to answer and I would've liked to have spent 12-15 hours on it versus the 8 I allotted myself. Because of my poor planning, I produced incomplete work and the completed work was NOT up the quality I usually produce and expect of myself. I did email my professor to ask for a possible extension and explain my situation. He would take off 25% for turning it in the next day, I did not take this option as I felt I could do better than that turning it in by 11 pm that night. 

I am embarrassed and humbled. My professor is a very nice guy and a great teacher. 

Would it be appropriate to schedule a time to meet with him to discuss the quality of my exam and how I would have approached it differently?

I am not looking for brownie points or extra credit or anything of the like. I just can't stop thinking about how I would have approached some of the questions differently. My ego took a hit and I'm essentially looking for redemption in a way.
Yes. If you would like to discuss the exam, schedule a meeting and talk with your professor about it. It seems that you have already discovered the core issues impacting your performance here - a lack of sufficient planning and the resulting lack of time - so it may be helpful to consider what you hope to learn from such a meeting. Are you hoping your professor knows some way to accomplish more work in less time? Are you looking for some confirmation that you really couldn't have done better? Your professor may have useful feedback but will likely agree with your assessments about planning.
