How to Master Conditionals

It is possible to master conditionals, prepositions and things like that. You will hear even native speakers getting them wrong - especially the third conditional. Once you understand the rules really well, then you might be able to kind of change them a little bit as long as you know that people can understand you. If it is sunny tomorrow, I will see my friends. This is my sentence. And your next task is to tell me what conditional I'm using.
