May luck still be with me

I will be having my Genetech prac test tomorrow. It's worth 10%. The procedures and calculations are simple but i hope i don't panic too much and screw up the whole thing. As to why i need all the luck i can get is that, even though i may be good with the apparatus and all, somehow during the practice run i didn't yield a very good result. I did the whole experiment twice and still got exactly the same answer. So i thought, it could have been the error of the pipette and i changed the pipettes before i left the lab. But knowing that my lab is on Wednesday and on every other days there are people using the same lab, everything might get jumbled up again and my lab partner and i might end up with that jinx pipette again. Pls pls, let me get an accurate result for my experiment and may i not be nervous tomorrow. Everything will be ok if i just takes things one step at the time. *hands, don't shake during the experiment*
Note to self:
# Check if the wave;ength on the machine is 595nm
# Check that the printer is on
# Check that the graph option was set to quadratic and the light is VIS
# Check that the spectrophotometer is set to the maximum height
# Prepare 2 reagent blank
# Make enough diluted unknown...make two sets of dilution, just in case
# Always add water before adding reagents

Wish me luck and pray for me ya? Thankz!
