How did everyone go? (1 Viewer)

Exam thoughts? Easy? Hard?

 

[Shadowfaxx]

Overall easier than 2017 and 2016. Except the frequent tricks NESA uses to fuck people over like eliminating outliers in titrates. Nothing exceptionally difficult ,people who route learn would of had trouble with a few of the multiple choice at the end.

That was really good. I changed my answer for the temperature from the right answer tho so now its wrong rip...
Lol well I think it was right.

Was pretty straightforward tbh, the 7 markers for both core and option (Forensic at least) were kinda vague but it was alright on the whole.

Weird flex, but ok

 

[whatafeeling]

I did better than expected but I disliked 7 marker and long responses for Forensics. I agree they were quite vague, I wouldn’t have minded if they were more specific

But I’m just glad it’s over, it my last exam.
Feels a bit surreal right now

when they said chromatography, did they want to compare all the different types or just the princples and applications behind them. I dicussed liquid chromatography in detail but just gave a few references to the other types eg.gas, but didn't go in extreme detail about all of them.

Anyone get 0.02 grams for glucose?

It's for forensic analysis so HPLC and GLC

 

[Powereaper]

I just wrote down everything I knew about HPLC,GLC and emission spectra for a whole page, before comparing them with another page.
What did everyone do for the 4 marker between reducing and non-reducing sugar?

 

[Joshfotho]

What did people get for the final temperature of the water? I got 90 something degrees, but really have no idea if I got it right

88 degrees

 

[bjw22]

I got 88 degrees after changing it from 77 - a few ppl said 77 was actually right so idk. I didn't talk about GLC AND HPLC, I just compared the principle of AES to chromatography, and used GLC as an example.

Last exam wowzers - what is this actually having a life thing of which people strangely speak of?

88 degrees

Do you wanna explain why the efficiency is 38% and not 40%?

Efficiency would depend on the value you got from your graph. But for every 20% drop in efficiency there was a 5mm increase in distance. So every 0.25mm =1% decrease, so for 3mm (45-48), = 12% drop so 50-12=38%.

Although my distance value for the graph was 48.2mm so idk if they’ll except that.

Hmm, well idk I'll probably only lose 1 mark, I don't mind c:
