You have 71 hours and 45 minutes to complete the exam.
This means that if your exam begins at 09:00 GMT, your exam will end at 08:45 GMT three days later.
Once the exam is finished, you will have another 24 hours to upload your documentation. Details on how to submit your files are provided below.
All OSEE exams are proctored.

NOTE: While you may use Discord as a resource for searching for information during the exam, under no circumstances are you permitted to seek or receive assistance from others on the platform.
The Certification Challenge consists of several target machines, accessible over the OSEE Exam Labs. You will access these machines in order to debug any vulnerable software using Remote Desktop.
Once you have exploited the target machines, you will find a proof.txt file in the Administrator's desktop directory. You must retrieve the content of these files and include them in your documentation together with your exploit code.
Please note that your exploits must be reliable and working code must be provided as our team is going to repeat your steps in order to grade your exam challenge.
You must document your attempts or attacks including all steps, commands issued, and console output in the form of a report, exported in PDF format. Your documentation should be thorough enough that your attacks can be replicated step-by-step and failure to provide sufficient documentation may result in points not being awarded.
The documentation requirements are very strict and failure to provide sufficient documentation will result in reduced or zero points being awarded. Please note that once your exam and lab report is submitted, your submission is final. If any screenshots or other information is missing, you will not be allowed to send them and we will not request them.
Please use our OSEE exam report template for your documentation. It can be downloaded at the following URL:

The objective of the Certification Challenge is to demonstrate creative thinking and success in exploitation of the victim targets.
The OSEE exam contains two assignments and points will be rewarded for partial or full complition of the given assignments.
Each of the assigments awards 25 points for partial completion and 50 points for full completion, thus the maximum obtainable amout of points is 100.
To successfully pass the certification exam, 75 points is required.
We have introduced a student control panel for exam takers.
Through this panel you will be able to revert your own exam machines, with a limit of a total of 50 reverts. Wait patiently for the machine to revert and only click the button once per attempt.
Note that reverting a machine will cause it to go to its original state and any changes you've made to it will be lost.
Details regarding how to access the exam control panel have been included in the challenge email.
This subsection of the exam guide documents what you should do in case you are unable to complete your exam due to severe external factors. Please make sure to read and understand it carefully.
The exam lab is a dedicated environment with no learners connected other than yourself. The total allotted time of 71:45 hours does take life and its situations into consideration:
- You are expected to take rest breaks, eat, drink and sleep
- You are also expected to have a contingency plan in the event that there is an issue outside your control. (e.g. ensure you have access to a backup Internet connection, Kali Virtual Machine, power etc)
If you have a legitimate issue, please send an email with your OSID to "challenges AT offsec DOT com" immediately. Make sure to include all the necessary details and supporting information such as a letter from your power company, ISP or any other relevant documentation.
Please note we are only able to extend the lab time if the issues were present on our side and only when the exam subnet is not immediately in use by another learners following your exam. In the event of an issue on our side and the exam subnet is scheduled immediately following your exam we will provide a free exam retake attempt. We work very hard to ensure our environments are highly available and issues are very rare.
If you encounter any connectivity problems with the VPN or target machines, inform us immediately. The preferred method of contact is through the live chat available at https://chat.offsec.com/ or via email to "help AT offsec DOT com".
Please note that we will not be able to assist with, or give hints on, any exam objectives and will only be available for technical problems during the exam.
All questions related to the exam documentation and submission, or other non-technical exam related issues should be sent to "challenges AT offsec DOT com". The live chat administrators will NOT BE ABLE TO HELP you with exam-related queries unless you are having technical issues with the VPN connection or exam environment.
