Commissioning Course Seniors

The following information was obtained from the 2012 Officer Candidates School Student Outline. Learning the material provided can significantly reduce the amount of studying you will have to do during Marine OCS. Of course, when the night before your test comes around don’t just rely on the information you think you learned months beforehand. Read these to get a general idea of what is taught, but you will need to know the details for the tests.

    I am still working through getting the rest of these up. Let me know if there is anything in particular you want first.

    1. Ben

      Hello sir,

      I am currently applying to OCS and was wondering what your run time was? I am currently running a 2230 which is a no go. Do you have a schedule or program you can offer to help me improve? Thanks

      1. USMC Officer

        I commend you on your desire to one day lead Marines. 22:30 is not going to be a great time for an applicant. At OCS, I would say the average is around 20:00 – 21:00. You will likely be slightly slower at OCS due to sleep deprivation and a change in diet (much less food … and practically no meat). Applicants definitely need to perform well, especially now in the midst of downsizing and cutbacks. I will put together some workouts this week so you can follow me on social or just check back later. However, I would like to leave you with a small quote from the most hard core SNCO I have ever known, “Workout plan? Just go out and f**king run”

        1. Ben

          Thank you sir. Where will you post it when you do?

          Also, will you have any advice on leadership?

          Thanks. I hope to be where you are one day. I hope you understand my anxiety.

          1. USMC Officer

            Your anxiety is definitely understood. Even the prior enlisted Marines at OCS with 5+ years of real experience find themselves being challenged.
            I have been reorganizing the main OCS page to make it easier to navigate. You should be able to find what you need, and I will continue to add leadership/fitness related content.

    Good evening sir,
    Thank you for putting all of this together, I have exactly two months until Seniors and the following knowledge is going to be extremely helpful and might actually save me an hour or two of rack time.
    I was curious about the specifics in each section and if you are going to put the rest of the Environmental Hazards up along with the others? I have a senior book laying around somewhere, but I prefer your more concise versions to the actual book.

    Thanks again and have a good night.

    1. USMC Officer

      Yes, I do plan on putting the rest up. However, I don’t think any of the other ones have tests associated with them (except uniforms and organization which I’ll add next), so I wouldn’t focus too much on those. They take a while to format so I’m just trying to do one every week or so. Environmental Hazards deserves zero attention. It just outlines some of the things that you might expect as OCS like bugs and snakes. It is one of the first classes you get and then never have to refer back to. The history classes are the most time consuming, because there is one test that covers all three sections.

  • Tommy

    This is awesome! Thanks so much. Looking forward to the info to come.

  • Paul

    Good Evening Sir,

    I am shipping out to PLC Seniors in two weeks and have a question for you sir.

    1) It is well noted that the knowledge provided on this site is from 2011, and it is subject to change. However, I was wondering if the history portion has changed at all sir? My PLC juniors knowledge stopped at the end of the Korean War. Will seniors start again from the Korean War like the knowledge provided on this site, or will it start from the Vietnam war sir?

    1. USMC Officer

      Unfortunately, I do not have a concrete answer.

  • Malik

    Good evening, Sir,

    I leave for Seniors in roughly a month and a half. I’ve noticed that some of the knowledge is still missing. I see that in a previous reply you’ve stated the ones up are the ones that deserve attention and the ones that are not, deserve no to little attention. I was curious if that was still the case, and if so do you plan on putting the remaining knowledge up?

    1. USMC Officer

      It’s a real pain converting the text such that it’s readable and organized. Also, the material I have is about 4 years old now. You will be fine learning the other material when you get there.

  • Alex

    Good afternoon Sir, I am a fully trained candidate and I am currently creating a website similar to yours for a class. I have no intention of launching it, or trying to compete with yours. I was wondering if I could use some of the resources you have up. In particular the knowledge. I am trying to make a resources page, but I could only find a few pieces online.

    1. USMC Officer

      No problem. Go ahead and use what you need.
