UMAT urgent questions - please help me!!

[tinagranger]

I have some questions about the UMAT and need help desperately!

1. The main thing I am really confused about is what the 'even-odd rule' is. Med Entry says that this is the best method to differentiate separate elements when there are 2 of the same element in a sequence - do you agree, and if not, what method do you use to separate out identical elements? (Because when I map all 10 letters on one map I get really overwhelmed and don't know where to start.)
I have re-read the med entry guide for the even-odd rule numerous times and it doesn't make any sense to me, so I was wondering if you could possibly break it down for me/offer me a tried and true alternative for these sorts of questions?
 
2. I read the student feedback from last year's UMAT on Med Entry and people talk about flow chart questions appearing? I have no idea what they mean about this and was wondering if you could give me some examples and talk me through what methods you are meant to use to work through these questions?
 
3. How do you find the average temperature from a line graph? (Also from the student feedback from last year's UMAT)

4. Do the questions that look completely new in the UMAT count? I have heard they don't, so should I just completely skip the S3 questions that look completely new? (I wouldn't do this for S1 or S2 because it would be harder to recognise which questions are 'new' or not)
 
5. My admission ticket says arrival time is 1:30 but there is no start time anywhere. I am wondering what time the test actually starts? Am I right in saying that they don't have a set start time, they just start when everyone is in the hall? Should I arrive before 1:30 just to be safe? Like at 1:15pm?

6. Do you have any tips on battling nervousness/being in top psychological condition on the day/general exam strategy?

7. I have found it really difficult balancing Year 12 with UMAT prep this year so have only done 6 full exams on Med Entry, so that's why I am feeling quite anxious, even though I know everyone is in the same boat! I usually get a raw score in the low 80s - do you know what this would translate to in percentile?

8. Section 1 is by far my weakest and I have found it really difficult to improve, so do you have any really effective tactics you could give me?
