Haroldo S. offers Biology Lessons, Chemistry Lessons, Geometry Lessons, ...

Teresa E. from San Juan Capistrano, CA I had Haroldo S. as a tutor for Organic Chem, and my sessions with Haroldo were not only extremely informative and helpful but also enjoyable. I especially liked having Haroldo as a tutor because he wasn't just about teaching the subject at hand; he was concerned with my overall performance as a student in general. Though Haroldo only tutored me in one subject, he was able to provide me with time management, test-taking, and study tips. He wants me to succeed as a student, and it really gave me confidence to know that he was genuinely interested in my academic well-being. I learned more during my time with Haroldo than I had the previous few weeks of the semester, and in addition, he gave me tips and skills I will be able to use for the rest of my life and academic career. Haroldo is an excellent tutor, and both helps me and wants me to succeed.

Sarah C. from Oakland, CA I highly recommend Haroldo for tutoring services. The fact that I'm spending time to write this review is testimony to my huge respect for his abilities. He is on time, comes prepared for each lesson, is extremely knowledgeable, and explains things well. Not only does our son greatly benefit from each lesson, but he gets along well with Haroldo. Haroldo also follows up with a detailed description of what was covered in the previous lesson, repeating what he told our son about how to be successful moving forward. He is a talented and responsible tutor. Thumbs up!

Dina O. from Berkeley, CA Haroldo was very helpful as a physics tutor. I really appreciated his tutoring style, rather than just giving me the answers, Haroldo would walk me through the problems in a way that I could easily replicate on exams. His test taking strategies and studying tips were also very helpful!

Julie C. from Berkeley, CA For students struggling in biology, I highly recommend asking help from Haroldo. His extensive research experiences in stem cells, cancer, and neurobiology allow him to provide students with great insight to many difficult concepts. Haroldo never makes studying biology appear to be simply a matter of memorizing what's said in the textbook, which is often the wrong strategy that hinders students' success in biology classes. Rather, Haroldo always attempts to relate concepts to various real world applications, ranging from actual research/experiments conducted by biologists to interesting debates surrounding some questionable basis of sci-fi movies. His teaching style well suits the recent trend of college biology exams, which heavily test students' ability to interpret experimental results or to even come up with own experiments that test hypotheses. Therefore, Haroldo's approach to helping students is no doubt extremely valuable, allowing him to succeed as a tutor.

Elaine L. from Alameda, CA Haroldo provides effective sessions that made a big difference in my son's understanding of the subject matter. He was making a significant impact on my son's understanding or test results in Chemistry during last half of school year. His Chemistry teacher was made a note on my son's test report with high score, "Where've you been hiding this skill?" I'm always impressed by how well prepared he arrives for his sessions and how thorough his explanations are. He will make sure my son to get the concepts in preparing for class, homework and tests. After each session, he writes me a detail email what he has taught my son and what he needs to prepare for class and next sessions. Now, Haroldo is tutoring my son for Preview AP Physics during summer to prepare for the coming AP Physics class in Junior year. I highly recommend Haroldo for anyone that needs the extra help! I am so appreciative of his support to my son.

Sachiko H. from Alameda, CA Haroldo helped my son's ACT test preparation. He helped my son to prepare for the science part of ACT, and he was great. He even came to our house the night before the test and the last minutes lesson really helped my son. My son was confident on the test day, and his test result was great. He got 35 on the science. We could not be happier with his services! Haroldo, You are great!

Ed E. from Novato, CA Haroldo is an exceptional tutor. Not only is he truly brilliant, he cares about his students and has a personal investment in their success. Our son regained his confidence and excelled after working with Haroldo. Our work with him was so positive, we are looking forward to working with him next year and over the summer for some prep work.
