Description
ATTENTION PARENTS: Does your student need help learning IGCSEand GCSEChemistry (or similar courses) from home?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 iGCSEChemistry and GCSEChemistry 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 IGCSEChemistry and GCSEChemistry masterclass they will receive access to:
NEW and updated IGCSEchem &GCSE chem video lessons for each section of the course.
FREE digital IGCSEchem &GCSEworksheets to support learning
FULLEXAMQUESTIONWALKTHROUGHS of past exam papers to help you learn the best exam writing strategies.
FREE topic-specific IGCSEchemistry past exam paper questions and mark schemes.
This IGCSEchemistry (O Level) masterclass is offered by IGCSEprep on Udemy. This masterclass covers all the content needed to write the IGCSEchemistry exams offered by Pearson Edexcel (double or triple)or Cambridge CIE (core or extended) or other exam boards like Oxford AQA.
