The problem of these tracks is that they have no landscape so it's not very easy to memorize them. However you can learn the succession of the curves by heart. For example for Syncopia (which is an easy track I admit ), remember : left, right, left, right, left, right right. Just repeat these in your head while you are racing and you'll get the "The Pure Four" trophy very quick wuthout a lot of practice You can also write down the directions on a sheet of paper and stick it next to your TV to watch it while you are racing (Mac Gyver technique). Hopefully you won't need these in the future
Hope this heps
