    1. I cannot begin to imagine the time and effort you put into making this blog, it is truly amazing and I can't thank you enough, you're a lifesaver so ignore any selfish crap comments you get. ps, you deserve a knighthood or something wow! x

    2. My guide has this one labelled as 'Recall', so I agree it doesn't need to be extremely detailed.

  5. His comment wasn't very rude, it was more like an observation. This is one instance where your work hasn't been very helpful and it was nice of him to supply a more informative source. But that is just my opinion. Thank you so much Hannah for all of your assistance though!

    1. DON'T GO TO THE KING FAHAD ACADEMY! IT WILL RUIN YOUR LIFE.
      The school does is not teach you anything and you have to self study. That's what i'm doing and I have to make up for their mistakes. Overall advice, don't go to the school
