This course will give them the skills they need to feel confident for their exams. Purchase this course to help your student prepare for their exams by helping them to understand chemistry, rather than focusing on trying to memorise seemingly unrelated facts.
This course covers all of the material studied in iGCSE Chemistry and GCSE Chemistry courses in the topics of Organic Chemistry, Reaction Rates, Equilibria, and Redox Reactions. These are normally the topics covered in (i)GCSE courses by schools in year 11 (Grade 10, ages 15/16). The material is also relevant for most GCSE courses. It is designed for students who are currently in year 11 (Grade 10, ages 15-16) and revising the material covered in their school lessons. It would also be useful for those students entering A level, or IBDP courses in chemistry who require a firm grounding before embarking on these more advanced qualifications. The material covered in this topic is also covered in most American and Canadian syllabuses in grade 10 chemistry/science (ages 15/16).
As soon as students sign up for this IGCSE Chemistry and GCSE Chemistry masterclass they will receive access to:
NEW and updated IGCSE chem & GCSE chem video lessons for each section of the course.
