Okay thank you!

In my answer to the question asking about determining whether the sample of propyl propanoate was pure or not, I ended up crossing out the entire answer (which took up all of the allocated writing room,) and rewriting my answer in 2 small dot points in a small nook above the question, with an arrow pointing to it. Also written in a different colour pen from the rest of the page.


The answer itself is fine afaik (just mentioned GC and regarding number of peaks present (and rt times compared to database)), but will the assessors be unmotivated to award the 2 marks if it is a bit harder for them to understand what/how I have answered?
Just a little worried that they will take off the marks because I made it harder for them.

No way! Assessors aren't allowed to penalise answers that are correct just because they feel like it.

I only hope that what I wrote in my frenzy was legible....

Also, in the explanation of any spectroscopic technique, I chose UV/VIS spectroscopy, and my explanation is almost identical to your's....but I made the silly error of saying outer shell electrons, not the electrons between covalent bonds....I'm guessing that's a mark gone. would that be a correct assumption? haha

If you get 80%, is it possible to get over 40?

[spongebob-7]

80% will most likely be a low A, so it is still possible to get over 40 if you destroy the unit 4 exam like get a very high A+

[datfatcat]

I think 80% is middle range A this year.
