Shooting: Points are given for scoring through the gaps within the net. You have to find the ""sweet spot"" to know how high to aim and how much power to put into the shot in order to do this. Gaps marked with a red 'X' are blocked. Later drills are also marked with a Goalkeeper.
To gain bonus points you can put Curl on your shots as you score. In certain Shooting drills you can also be awarded MPH bonus for speed and also a Streak bonus for scoring consecutively. You can find out more about Curl, Power and Streak bonuses elsewhere in these FAQs.
Here is a handy video describing how the Shooting drills work:
