Hi Christopher,
If I had some spare time I would be happy to help you out. Unfortunately my spare time is very very limited to race.
As the others mentioned, just join sessions. You can just join session and first watch how others drive around the track. Select other drivers, change to cockpit view and try to learn how they drive.
Don't try to watch the aliens but begin with watching how an average driver takes the corners. If you are slower then average, begin with that part first. Some aces/aliens drive such high level, we normal humans will never achieve.
I do exactly the same. Since yesterday the Skips drive at Zandvoort. I practiced till I did a reasonable lap, which was 1.58.high. I just entered an online practice session to see what laptimes I should have. Initially i was happy to only be 0.5 from the current fastest time, which was 1.58.0x. Then some alien entered the session and drove consistent 1.55s. I viewed him driving and I already knew it was beyond my capabilities, unless I have hours and hours of spare time. But I tried doing the same cornering and lines during various corners and my times dropped to 1.57s. Still 2 seconds off pace, but good enough for me.
The biggest thing in iRacing is to drive consistent, slow or fast is not important. Drive your laps and have fun. And watch your mirrors for superfast dudes. The F3 info screen helps to see who is lapping you and how far away they are.
As said, practice enough and try to join some RD events. They will not harm your safety rating
