To get this achievement, you will need to attain all 16 track stars on ALL 20 levels. Also, you will need to make sure to get at least a silver medal on every track. Silver medals shouldn't be too bad, and if you're struggling just practice and try follow the Gold ghost. As for the help with track stars, I've made a video series showing all of them, look below:

Please note that I did NOT use any power-ups, although they can be purchased if you want. Also, you will need to buy all the split paths. Hopefully this is helpful. If you need help, leave a comment!
