Certified Tutor in General Chemistry and Organic Chemistry with 3 years of experience

Ótimo professor! Entende muito do assunto, tem uma ótima didática e é super paciente!
Super recomendo!

O Marcus é um excelente professor! Me deu aulas de química no ensino médio, eu estudava no CP2 e ele me garantiu ótimas notas nesse período. Hoje, também como tutora, recomendo totalmente seus serviços, pois o reconheço como um ótimo profissional. :)

I really enjoyed my time being tutored by Marcus. Before I had been a bit behind in my class, and I was really struggling but after just a few sessions I began to see improvement, especially because he was so good at explaining and simplifying the material. Marcus is a very friendly and personable tutor and makes the sessions fun. I highly recommend him!

Marcus is a chemistry genius! I made sure to take two tutoring sessions with him before my organic chem tests and I aced both of them. His way of teaching really sticks with me.

I strongly recommend Marcus as your chemistry tutor, especially for those struggling with high school level(AP, IB) or college level chemistry classes. I had a very hard time with organic chemistry. But I started working with Marcus and not only did my grades improved significantly, I also came to enjoy organic chemistry as well. Thank you Marcus, and I hope you all get the chance to work with him too because he is a great tutor.

Marcus is amazing! Teaches in English and Portuguese. I learned so much Chemistry from him and he answers every question you have. He is definitely worth it!

Marcus is a wonderful tutor. I had to take Chemistry as a requirement for graduate school and he helped me tremendously. Not only does he know the material very well but he was able to explain it a simple way that helped me to better understand it. I could not have done as well in the course as I did without his help and support. I highly recommend him!

Marcus has helped me a lot in organic chemistry. He is very knowledgable and responsive. He is able to explain the concepts in very fundamental ways. Very reliable and would highly recommend!

O Marcus é uma das pessoas mais inteligentes e dedicadas que eu conheço! Merece toda a confiança dos alunos! Com certeza vão adorar suas aulas. Indico a todos!

My daughter has taken her trial lesson with Marcus. She does not have confidence in learning the AP Chemistry subject due to having a gap of one year without learning any Chemistry topics. However, after going through her trial lesson, Marcus has successfully ignited her interest and at least gives her some motivation to learn. She has also taken the initiative to schedule future lessons with Marcus. As a parent, I am pleased with the constructive feedback that Marcus provided. I am looking forward to seeing my daughter progresses in the learning of Chemistry with Marcus's guidance.

Marcus foi um professor muito dedicado. Ele esteve atento às minhas dificuldades particulares e, por isso, pôde contribuir de forma efetiva para o meu aprendizado!!! Além de que ele é uma pessoa inteligentíssima e com conhecimento muito amplo da matéria. Sinceramente, nem sei se teria me formado se ele não tivesse me ensinado... Super indico !!!
