Do Atlanta...its a good track. From my experience on it (I have driven both Star Mazda and Skip on this)..
Turn 1, this is one of the harder turns, very tricky, you can easily understeer and end up in the gravel pits or understeer and smack into the wall. Its also tricky as its the exit for the pits so a lot of accidents here. Its also wide enough for some aggro drivers to go easily 2 or even 3 wide here right at the start so my suggestion is not to go mid pack here. Qualify for the front grid, or if you see that your mid pack - think about starting from pit lane,,.
Turn 2, this is where you can get 1x if you want to shave off some time or simply because you totally missed the apex. Not going to go into the debate of whether this is "illegal" but yea..just pointing it out, cop a 1x and you can gain a lot of speed here without any warning flags.
Turn 3, 4 Esses, pedal to the metal.....if your not, your doing it wrong.
The rest is quite easy and I won't go into detail with...until.
the final chicane, get comfortable and know your braking zones here, make sure you can hit it time and time again because you can make up so much time here against others and if you get your exit speed optimal, it will lead to a very easy overtake when you go into the last turn and head down the home straight. (I almost won a race here but I chcoked, ha!, and lost the race by 0.7s).
Good luck.
