IGCSE Biology ( o level) for high school students who wish to have quick revision and solve past papers before exam. Hi there! My name is Dr Jad, i am a medical doctor and I've been tutoring medical students for 2 years, and high school IGCSE biology in Kuwait for more than 3 years. I have a wide range of knowledge in biology and medical sciences. I teach in a simple, comprehensive way that is easy to grasp by all students. I believe that practice makes perfect, therefore each topic taught is always followed by a myriad of questions and past paper solving.
