Release time: 11:30 am on Saturday 12/12/2020 Due time: 11:30 am on Monday 12/14/2020
Length:​ ​3 hours and 10 minutes​ from the time you start the exam. We offer people 10 extra minutes to count for potential internet issues.
The final exam is open book, open notes, open compiler, and open internet. We want to stress that the open internet policy allows you to search for java doc only. No other websites are allowed. No posting on any online forum or social media other than our own piazza site. We do not answer any questions during the entire exam period. If there are any ambiguities or typoes in the exam, we will take care of that when we grade the exam.
Our piazza site will be set to private post only during the midterm period.
You should always select the best answer. For example, if you are supposed to select a single choice for a question and there are multiple correct choices and there is a choice stating that multiple choices are correct, then you should select the choice that states multiple given choices are correct.
The sample ​final exams​ are from 8B. Certain topics including multi-threading, GUI, or vim related questions are not covered in 11.
