About Me
Good!
My name is Jesús, and I have a degree in Biotechnology and a master's degree in the same field. Biology has always been my passion, and for years I've tried to learn as much as possible, both academically and through self-study. I believe it's one of the most fascinating branches of knowledge, with strong connections to other disciplines, and a field with enormous potential for future development.
My primary goal in these classes is to help you resolve your doubts and understand your academic material as clearly as possible. I like to prepare each session in advance, focusing on the specific content you need, so that the class is as useful and personalized as possible. I can teach from primary school level up to the first years of university degrees related to Biology or Health Sciences.
Besides biology, my second passion is languages. I've learned several on my own and hold an official C1 level certification in English, which allows me to offer practical English classes: conversation, comprehension, vocabulary, and writing, adapted to all levels. I don't focus on advanced academic grammar, but rather on the real-world use of the language and improving the fluency of Spanish students.
I also offer Spanish classes for foreigners. As a native speaker, I can help you improve your conversational level, comprehension, pronunciation and written expression, always from a clear, practical and natural focus. I can also teach Biology in English if needed.
I hope to hear from you and that you enjoy my classes, whether it's biology, English, or Spanish. My goal is to help you progress, better understand the topics, and, above all, enjoy learning.

I have a degree in Biotechnology and a Master's in Biomedicine, and a C1 level in English. I've been passionate about biology since childhood and have been studying it for years, both formally and independently.
I offer classes adapted to all levels: from the most basic content taught in ESO and Bachillerato (classification of living beings, zoology and botany at an introductory level, the cell, genetics, ecology, evolution, etc.) to the most advanced topics, typical of university studies, such as microbiology, biotechnology, biochemistry or molecular biology.
My goal is for you to understand biology clearly and logically, using practical examples, solved exercises, and real-world cases to make learning dynamic and tailored to your needs. We will develop critical thinking and the scientific method so you can confidently tackle your exams and studies.
I can also teach biology in English, including general biology, cell biology, molecular biology and related fields. My classes are clear, adaptable and suitable for both high-school and university students.
