i have posted several questions? and NON have gotten help? :(
WHY is everyone else getting help and NOT me? HELLOO???
Our chemistry tutors aren't online right now.
I do apologize then, could you let me know when they will be so maybe I can get help then?
One is on vacation and probably won't be online, but the other comes online in the late afternoon/early evenings.
thank you!!! :))
