Is it normal to feel like they tested everything except the things you nailed??

Yep. In 2017 a bunch of us spent heaps of time the night before going through specific immunity and then didn't get any short answer questions on it haha

Was there anything surprising?

Was there an article question this year?

Pretty easy and straight forward exam...

I've heard that from a lot of people. Bit surprising given people did quite a bit better on the 2018 exam than the 2017 exam. Would have expected this one to be at least as difficult as 2018 again.

What did you guys put for the Zika virus question as to why they couldn't correctly identify the antibodies?

[DBA-144]

Definitely much easier than 2017 and 2018. Didn't stop me from messing up on expression throughout the paper however

I wrote something about the constant region of antibodies being similar and the differences in antigen binding site being very minute and small... probably wrong though.

Funnily enough, found it much harder than 2017 and 2018. I made some silly mistakes...

What was the one where they transcribed the structural gene and it said what molecule does it make?
Options were
Repressors
Transcription factors
Lactose
mRNA

I stupidly changed Question 8 in Multiple Choice that was about the dependent variable from percentage of bacteria coverage to amount of bacteria

What was the answer to the limitation question?

[IThinkIFailed]

What was the answer to the limitation question?

I said that the environmental temperature was not controlled, so it could be fixed by doing the experiment in a room with a controlled temperature.
