The reinforcement worksheets are based on new syllabus content of Cambridge IGCSE and Cambridge O Level examinations. The worksheets cover up the topics of formulae, functional groups, isomers, naming and fuel.
The reinforcement worksheets are based on the topic alcohol based on new syllabus content from 2023 to 2025. The worksheets cover up the naming, reactions and manufacturing alcohol .
The reinforcement worksheet of exam style questions is based on the specification and is included the questions on properties, chemical reactions , manufacturing and uses.
The organic chemistry reinforcement revision worksheet based on exam style questions are for Edexcel International GCSE (9-1) specification. The questions are included about properties, reactions, naming , uses and polymerisation .
The reinforcement worksheet is based on new specification and the topics homologous series, naming and formulae of basic concepts of organic chemistry are included . The chapter crude oil and cracking and fractional distillation of crude oil is added to the introduction because most of questions are linked between two chapters.
The reinforcement revision worksheet is based on the topic polymers and polymerisation of the new specification of Cambridge IGCSE and Cambridge O levels. The worksheet provide and basic concept of polymerisation and how to draw seen or unseen polymers according to the given monomers.
The booklet is based on new specifications with sufficient practice questions
to enhance the application knowledge of students.
