Typo in title. Should say 17th

After the biology exam, I'm pretty much expecting anything at this point.

Hey guys, I thought it actually went really well! Nothing unexpected this time and I answered all questions properly!

What did you guys think?

I believe this is Triple Science (so separate science) however, you are perfectly right, it has not been specified.

I liked that one exothermic, bond question where you pretty much had to form and solve a linear algebraic equation.

That's the bond energy question, right?

What did you get for it? I'm pretty sure I fudged it up really badly.
I got something like 800?!

But overall, I'm so happy!

Uhm... That question was pretty much a "show that" question where they wanted you to show if it was either 432 or 411. The actual answer was 411.

Exactly!!
I was wondering where the hell I went wrong but I think I forgot to factor in one of the bonds which is really silly... but it's me but I'm honestly ok with this...

I got 411 for the C-H bond too.

What do you guys think in terms of grade boundaries? I reckon i got 70-80%, will that be enough for a 7?

I got 411 but instead of working backwards I just substituted in both values and concluded 411 was correct. Is that a legitimate method for 4 marks?

I'm sure that would be fine. After all, you did prove which one was right regardless which method you used. Don't worry about it

No 80% seems absurd for a 7, it’ll most probably be 65-70%
