Welcome to PF!
Which state are you from?
We shall surely help you in your questions. I recommend you to go through the following main sections of PF, and explore them:
1. The main forums, that you see in the first page.
2. Insights Blog, available at the top row (header section). In short, they have been described as a "wonder of the web". It contains articles that help in learning topics to a great extent.
3. The Videos, also available in the header section. The media gallery now has some great videos in almost every aspect in science, and they provide an audio-visual learning experience.
You will find a lot of information in the last two, in addition to the first one. If you've got questions, post your question in the correct thread, and we shall surely help you out.
With regards,
Wrichik
