Hi.
I've just completed two rounds of my biology spa exam and there
are just some questions that really require the answers or else
I'll just feel bad for the rest of my life.
Okay, so firstly, in my skill 1 and 2 spa exam today, I made a
mistake in one of the questions in my report. However, besides
that, my answers were pretty much correct. I would like to know
whether this mistake would cost me my A1 grade greatly, since spa
exams are 20% of the total marks. In addition to this, I am not
confident for my answers in the first spa exam. Also, can you
please kindly tell me how much a wrong answer costs me?
Secondly, I was wondering if my skill 1 assessment would be
affected as my lighter for the burner wasn't working, despite
subsequent tries to light a flame by the examiner. Does this cost
me my full marks for skill 1?
Also, I was thinking, what are the sources of errors in
titration, given that the reagents do not contain impurities?
