Generally depends on the School Leaders (esp. the P). If you've seen it done at your school, then yes you are getting a rawer deal.

But as someone shared earlier - if you're looking for a chance to prove yourself without changing school, this is probably it. If you last got C (not even C+), don't think it's realistic to expect immediate appointment. If you're willing to work harder for a chance to shine, go ahead! If not… well, plenty of people find happiness as HOTs, too!
