GAMSAT first sitting advice

I am sitting the GAMSAT for the first time next week and I'm feeling super nervous, underprepared (despite months of ?unproductive study) and overall unconfident in myself. I can't seem to shake this and the practice test results I'm getting are not helping my confidence. I am dreading it! I know that I have worked myself up too much and it's probably going to be my major downfall on the day!

I know it's my first sitting but I fear my results and performance may discourage me from trying again! I just feel I can never get in the zone and I am constantly stressed about getting the questions done in the time rather than reading the text properly, leading to me choosing the wrong answer.

Any advice is greatly appreciated! Anyone who has been in a similar situation and has come out the other side?

Thanks and good luck to everyone next week!
