Hello everyone, thank you all for your replies and suggestions :-).
To be honest, in all this time, I have never seen the windsock on final! I am trying too much to focus on landing rather than look elsewhere other than the runway. Next lesson I will make an effort to look for it! :-D
I do check the METAR every day even at work just to get my head into that different "language" and try to calculate the crosswind from that then check if I am correct. This helps...and it also helps that I am in the comfort of my desk haha.
I like the sound of keeping things simple by using the 30,45,60 rule, but for the exams I better practice the more accurate methods. I guess practice makes perfect. My limit is 17kts and fortunately (or unfortunately as it could be good practice) it has never really been close to the limit. I haven't really done any serious crabbing either...I think I will get a shock when I will have to haha.
Thanks again for all your replies. So helpful!
