I have biology teaching experience in Iran for the students that were studying for the University entrance exam. As a medical student biology is the subject I'm trying to know more about and also the most I know about. I can help u study Campbell and fall in love with biology and it's interesting field. I believe that memorizing the facts is not enough and the best way to learn biology is to answer two questions about those facts which are "WHY" and "HOW". When you try to answer those questions you will come up with new and more ideas and you'll essentially understand that biology fact. Responding those questions sometimes requires specific knowledge and you'll need someone who knows about biology, in other words you'll need an expert. Well I'm not trying to say I'm an expert but I have read alot about biology so I can help you with that. In addition I would like to say this method of teaching will leads you to doing researches and learning will be more interesting while you are doing it as a researcher so trust me I will do my best to help you with that. If you are tired with old methods of teaching but you love to gain knowledge and study like a scientist talk to me!. Studying is much easier than you think you can enjoy studying as much as playing a fantastic game or having a delicious meal. Everyone has the right to educate and gain knowledge it's not about the intelligence level of people or their financial situation, it's solely depends on their will to study.
