I figured so ... Looking over your posts, it seems you are in University in your country. What may be wise is to post accordingly here. As a university student, you should have the skills to perform research and write with a certain depth on topics. You should apply the same here on this forum in a sense, and start to build a decent posting history for yourself (avoid all those one-liners youve got as much as possible).
You tend to post in the Services section, which I barely visit, and can therefore not give you specifics as to what to do or not do in that section. Beginners & Help may be a decent enough section to post in, where youve only got a few posts so far (the Guide for Ranking Up you created went the wrong way, since you included information that is already on official threads and overdid the colour stylings).
You do not have to turn into an expert in a specific area overnight, but you do need to be a bit patient (your posting history only goes back one month; I took nearly two to get my first merit) and above all Id say do what I stated in my first paragraph.
