I wouldn't say that you should be "worried" but at the same time if you just fill your apps with a clear and open mind you will be ok. In case of any doubt just ask here and I am sure there would be a lot of nice people who would guide you accordingly.
I started here almost 5 months ago and like you had many doubts and questions. You can also get a lot of help by searching and reading previous answered questions similar to yours. I know because this was what i did almost everyday. This board has become my second home
