Make tests in FL Studio. That's how I learned and now I know how to make average tracks! (I was a total newbie when I started)
Try making few covers to learn how to use effects or instruments/samples. Take a MIDI file and try to change instruments, using various samples and effects, and you'll learn how to use the basic functions of the software.
I did dozens of covers to learn chords and stuff, and see how each effect worked. Patience is needed, but you'll thank yourself to take your time learning basic things.
EDIT: Also, take a look to guides like zircon's or Rozovian's (you can find the latter in the Recruit subforum)
