Biology 101: A Complete O Level Course

Prepare for GCSE, IGCSE, AQA & CXC Biology examinations

What you'll learn
Understand how organisms interact with their environment
Understand how the human body functions and protects itself from diseases
How to answer examination questions effectively
Requirements
You should have a basic understanding of Scientific principles
Description
Are you preparing for an upcoming Biology exam? Do you have difficulty in understanding basic biology concepts? Have you taken online courses with inadequate opportunity to test your understanding of concepts? Then this is certainly a course for you to enroll in.This course will serve as a revision guide for High School Biology or Human and Social Biology students. The contents that are presented were mainly based on the CXC syllabus, effective 2015. However, the content is also suitable for students who are studying for GCSE Biology or similar "O" level examinations. This is a comprehensive Biology course that touches on almost all of the contents that students must be able to understand for their examinations. More than 90% of the content is presented in short videos (not longer than 10 minutes) that concisely explains the concepts. Additional contents are provided in the form of notes that can be downloaded in the resource section. These notes are intended to extend student’s understanding of the concepts. It is expected that students timetable themselves, to spend at least 60 minutes a week to review the contents in order to be fully prepared for their examination. Besides viewing the videos and reading the additional notes, it is expected that students complete all the quiz. A practice exam was also added to test your knowledge of the entire course. I am certain that after completing this course, you would be able to fully prepare for your examinations. *Please note that this course will continuously be updated with additional lectures, or edited lectures.
