  1. Thank you for this article.
    Please my question is about Direct posting. Is direct posting done during registration or after registration

  2. Thanks for ur article, buh am confused about revalidation.

    My question is, are those that registered for batch A stream 2 going to do *Revaldation* even though it’s not our fault that we didn’t attend orientation camp after mobilization because NYSC THEMSELVES shited us to another batch.

    1. Ordinarily, PCMs who are moved into the next stream don’t revalidate. This is because revalidation doesn’t apply to different streams within the same batch. But this is the first time PCMs will be moved from a batch to another batch entirely so I guess you will need to revalidate so that your call-up number can change.

      Be that as it may, revalidation is a straight forward process that can be done on your mobile phone. Hence, there’s no need to worry because I’m here to walk you guys through the process when the time comes.

      I hope this answers your question? Let me know if you require further clarification.

  3. Thank you for this detailed article. I appreciate the effort you put into explaining these terms and slangs in a clear and concise manner. Please how can we apply the skills and knowledge we gain during our NYSC experience to our future careers and personal lives?

    1. Hi Naomi, there is no one size fits it all for your question. What works for one might not work for another. I’ll advise you engage in the SAED class you are most passionate about. For example, if you are enthusiastic about fashion, then tailoring might catch your interest. That way, the skill will always be useful whenever you decide to pursue your passion.

      1. Thank you so much for all you’ve been helping us forge ahead, and be directing us through the right part, am really grateful;
        Pls how can one know when to do the revalidation to join the next stream
