I am posting this here, with Tim's original answer, as his profile says it is better to post quiz questions here. We are still Moodle 2.8. Can still use some database logs help.
ORIGINAL:
We have a student that took a final exam. She said when she clicked "submit" at the end of the exam, her multiple choice answers were blanked out, but the essay questions were fine. I have looked at the log file, I can see that she was in the exam for an hour and 40 minutes. No where in the logs did it show she had any MC answers selected. Where else can I look? She has filed a formal grade appeal.
Thanks
Harold

Tim's Response:
Do you have auto-save turned on in the quiz settings? https://docs.moodle.org/35/en/Quiz_settings#Site_administration_settings (I cannot image why this would be turned off.)
As well as the Moodle logs, you can look in the Apache web server logs (try filtering by the IP that the student was using). There won't be a lot of information there, but it is a very low-level of logging, so very reliable.
Also, as well as the logs in the Moodle database, you can use this query: https://docs.moodle.org/dev/Overview_of_the_Moodle_question_engine#Detailed_data_about_an_attempt

My Follow-up:
Thanks for the tips Tim. Autosave is turned on and runs every 2 minutes.
I looked at the apache logs, nothing for her IP in the error logs (good!) Access logs show her in the quiz, and I see the /mod/quiz/autosave.ajax.php runs fine.
Can you give me some examples for the database? My mysql experience is limited.
Thanks again!!
