Hi I’m Serena! Having achieved the top grades at GCSE and A-level, I am excited to help others do the same. I have been tutoring Biology and Chemistry online for over a year and I have enjoyed helping my students to improve their grades by covering a wide range of topics, providing revision tips, and trying practice exams. My classes usually consist of one or two topics per lesson, along with some practice exam questions at the end relating to the topic covered. However, lessons are flexible and catered to the needs of each student so I am more than happy to go over particular topics or questions requested by students.
