Hello, my name is Arturo, and I am a guy who graduated with a master's degree in Chemistry, both from the UCM. I teach classes on science subjects (Mathematics, Chemistry and Physics), either online or at home. I am passionate about chemistry and writing and I love sharing this passion with others. I have recently taught English classes and my students usually encourage me to open the range and give private classes. I have no problems teaching classes to adults. In fact, my last students have been adults. I live in Madrid.
