I got through that and it was not an easy matter to understand them well although they were a favourite subject of mine.
After some years of jet flying and using computerised EFB performance, I have sometimes to really dig in the books again to clean up things on my head, mostly due to the fact that no one is talking about performance these days. You get a number, we are good to go. The ideas that ppl sometimes discuss in the cockpit are non sense mostly because performance these days is teached but very rarely properly applied and discussed in the cockpit unless there is an obvious reason. But a/c these days are so overpowered that make ppl stop thinking about it
