I specialize in giving courses for Biology, English ad Chemistry. I aim to prepare students for tests, or to help them improve their skills in case they face challenges in the understanding in these materials, trying to make it simple and easy and fun to learn. A dynamic interaction and communication are two keys that i look for during my classes. First i help in the explanation and later i encourage the student to solve homework , in case he or she faces a difficulty i help him or her to think and find the answer.
