I bought this test kit a while ago and do not like the little spoon part of it, never know if I added too much or too little, do you have a trick to level that tiny spoon?

LOL I agree with you. I usually triple check the amount on the spoon.
 
Heap the amount on the spoon, as you take the spoon out of the bottle, tilt the bottle and scrape the top of the spoon on the top edge of the opening of the bottle.
