On the level Cosmic Wall wit Dr. Robo, i keep getting B ranks when im getting 90000 points when numerous guides say 80000 is an A. Please tell me this isnt a glitch. BTW, is it true that u get an auto A-Rank if you get all rings in a level? I have like 7 A-Ranks left to get b4 I score Green Hill Zone. Thanx In advance!
