Grade points are earned by entering division races (1 per event maybe two if it’s a double up and you participate at both.) National events (where the Pros run) open for online registration before the event. There usually is a field quota for each class set by NHRA (can be different from race to race) Racers with the required grade points from the previous year are allowed to enter first. (Starts around 8) then after a certain number of days it drops to 7 then 6 and so on until the event quota is reached. Past champions and alternates can result in more entries than the quota. Chances of getting into a National event with only 2 or 3 grade points is slim in most cases with a few exceptions.
Hopefully I got this out there correctly, there are a few more ways with withdrawals and exemptions but that’s about it in a nutshell.
