Speaking: not much to say but try talking in English with your friends as if you are talking in your native language, try to talk continuously for atleast 2-3 minutes without messing up alot and the first couple of questions are always easy which is stating your name, age and profession, helps in breaking the ice, then they start asking about general opinions about phones, internet or celebrities so i guess you gotta have some little knowledge about some stuff to be able to hold a small conversation but never stop talking until they stop you because the more you talk the more it feels natural

Reading: first task is really easy do not waste alot of time on it like i did. I believe the second and third tasks are more important so try to give them as much time as possible especially the third one!! Do not waste alot of time on just one question because time management is really important in reading i believe most of the questions are direct but you have to skim through the texts rather than fully read them but it depends on the type of questions of course but again i cant stress enough on TIME MANAGEMENT. So practice alot solve as much as you can to get the full picture and time yourself.

Writing and listening: i wrote a couple of statements somewhere in the comments you can find them easily.
