It's always good to learn the melody. Slow it down and practice listening and playing at a speed you can manage and understand. Use the difficulty slider to dial out extra notes if you need to. Then try out some licks! There's some beginner licks and some nice intermediate variations. If all this is easy try using hide notes to learn by ear and memorize. You can do this with the main arrangements and licks. Remember learning by ear can be tough. Use the tempo slider, difficulty slider and focus features to learn in pieces and at speeds and difficulty levels you can handle. Just cause you can play a difficult tab piece by reading does not mean you should try to learn difficult pieces by ear, especially if you are inexperienced. Start simple.
