This is what I found in a search........
1. Go to the Navy Knowledge Online website at:
https://wwwa.nko.navy.mil/
2. If you do not already have a NKO account, click on the "NKO Registration" link and follow the directions to establish an account.
3. Once you are logged into NKO, click on the button for "Personal Development" Then go to "My Education".
4. On the "My Education" page in the upper right hand corner there is a graphic showing some motivating Navy pictures and the text "CLICK HERE TO ACCESS NAVY ELEARNING". Click on this picture to take you to Navy eLearning.
5. On the Navy eLearning page there is a menu down the left hand side of the screen. Click on the bottom button "Advanced Search"
6. On the search page click in the box under "Course Title", enter "OCS", and click the "Search" button.
7. Four topics should come up: OCS Service Etiquette, OCS Naval History, OCS Military Training Requirements, and OCS Physical Readiness Training.
8. To subscribe a topic click on its name and then click on the "Enroll Now!" button.
9. Once you are enrolled in the topics, click on the "My Enrollments" tab on the top of the screen.
10. From the "My Enrolments" page you can click on the "Launch!" button to take the course or click on the "Progress" button to check your current progress in the course.
The Naval History is 9 chapters and will take a while to do. You can print out the Studyguides to help prepare for the Exam (reading on the computer hurts my eyes after a while). It is good to have as you are going through the lessons. The other 3 can be done in about an hour each.
hope this helps
