Again - great job on using the test kit for the first time.
It is always a dauting process initially but suggest you look at these videos
The TF-100 sets the standard for excellence in Pool Testing Kits. It contains 7 separate tests to give you accurate readings on each important pool water parameter.

Also, if you just want to practice, do the Alkalinity test again. remember that one is a 25ml sample and the color change should be to a cherry red - on my testing it goes to a pink/purple then on next drop it is cherry red. Just to give some clues to look for.
Good luck - Marty has you well covered on the SLAM process.
