Frequently Asked Questions
What are the Chemistry HL Key Concepts?
The IB Chemistry HL Key Concepts section is one of the four main features on Revision Village for Chemistry HL students (in addition to Questionbank, Practice Exams and Past Papers). The Key Concepts section includes a carefully planned set of Chemistry HL Exam Revision Videos that students can use to refresh specific concepts (e.g. Hess’s Law) that they may have missed or misunderstood in class. The revision videos typically range between 5 and 10 minutes in length and are a short and concise way for students to quickly refresh a concept, before practicing exam questions, either in the Questionbank or Practice Exams section of the Revision Village website.
How should I best use the Chemistry HL Key Concepts?
A great way to improve in Chemistry is by practicing lots of questions, but sometimes we forget key pieces of theory. It’s recommended that students use the Chemistry HL Key Concepts in conjunction with solving exam questions. Stuck on a specific question? Go to the Key Concepts section and watch one of the revision videos that recaps the theory. It’s recommended that students then return to the original question and try and solve it again.
Do the Chemistry HL Key Concept videos replace my textbook?
This is not the aim of the Chemistry HL Key Concept section on Revision Village. These videos are short and concise and aim to ‘recap’ the theory, as opposed to teaching and explaining the theory, which is the purpose of textbooks. The Chemistry HL Key Concept section on Revision Village aims to support students’ revision process by providing an easy way to quickly recap the concepts that occur frequently on IB Chemistry Higher Level examinations.
Who are the teachers in the Chemistry HL Key Concept videos?
The Chemistry HL Key Concept videos on Revision Village are taught by experienced IB Chemistry teachers and examiners, who are passionate about teaching IB Chemistry HL concepts in a simple, intuitive and engaging manner. The team is dedicated to helping each and every student achieve their best possible IB Chemistry grade.
