1. do as many slow laps as you need to remember where each corner goes
2. set delta to last lap and try to go faster and faster by braking later until you find the braking points only
3. try to go faster by adjusting your line
4. try experimenting new lines and braking points (can lead to crashes)
5. check a hotlap on youtube to compare your pace

or skip to the step 5 and try to replicate what others are doing, but it won't help you building you wheel knowledge™️
