Description
ATTENTION PARENTS: Does your student need help learning IGCSE and GCSE Chemistry (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!

Full syllabus coverage details are available in a downloadable file for iGCSE Cambridge/Edexcel/AQA, GCSE Edexcel/AQA, and O level Cambridge.

This course covers all of the material studied in iGCSE Chemistry and GCSE Chemistry courses in the topics of Acids, bases and Salts, Reactions of Metals, Identification of Substances, and Energetics. These are normally the topics covered in (i)GCSE courses by schools in years 10+11 (Grade 9/10, ages 14/15/16). The material is also relevant for most GCSE courses. It is designed for students who are currently in years 10/11 (Grade 9/10, ages 14-16) 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.

FREE digital IGCSE chem & GCSE worksheets to support learning

FULL EXAM QUESTION WALKTHROUGHS of past exam papers to help you learn the best exam writing strategies.

FREE topic-specific IGCSE chemistry past exam paper questions and mark schemes.

This IGCSE chemistry (O Level) masterclass is offered by IGCSEprep on Udemy. This masterclass covers all the content needed to write the IGCSE chemistry exams offered by Pearson Edexcel (double or triple) or Cambridge CIE (core or extended) or other exam boards like Oxford AQA.

Who this course is for
iGCSE and GCSE students studying double (core) or triple (extended) award chemistry or courses for the similar age range
