Disease Detectives and Science Crime Busters

[madscientist]

last time i was in science crime but just a little tip bring lots of reaction plates they let you wash them your first competition of the school year but after that anytime you need to wash your plates you can but they take away 5 minutes from your time

so i'm doing the two events also (my first year)
but, i still don't get the rules for both
in Disease Detective, I can't find any good practice tests other than the CDC EXCITE
then in science crime busters, is there any practice tests? also, do we have to test every single combination of the solids?
any help would be appreciated

for science crimebusters
its recommended that you do test every solid, and it will help you but if your on a time crunch i wouldn't worry about it too much, out of all the compitions I've been to the most they ever had was 3 mixtures out of like 20 solids so it up to you
