ISC Class 11 Chemistry Paper Pattern

Students can refer to the latest ISC Class 11 Chemistry Syllabus on Extramarks. As the exams approach, it is essential to revise all the concepts and definitions. One paper of three hours duration is divided into two parts. 

Part 1 (20 Marks) is a compulsory section where the student has to attempt short answer questions. This section will test their knowledge, application, skills relating to elementary/fundamental aspects of chemistry. 

Part 2 (50 Marks) is divided into three subsections A, B, and C. The students can answer two out of three questions in Section A (each carries ten marks). In Section B, they can attempt two out of three questions, each carrying five marks. Further, in Section C, two of three questions each carry ten marks. Thus, there are a  total of six questions in part 2. It is essential to practice before the first-term exam. The student may refer to ISC Chemistry Class 11 Syllabus for more information. 

Students may access the below study material on Extramarks to help them prepare for the examination.

ISC Class 11 Chemistry Syllabus & Study Materials 2023-24 

Students can refer to ISC Class 11 Mathematics Syllabus & Material on the Extramarks website. They can start their preparation for the first-term and competitive entrance exam. Further, the students will get an introduction to basic concepts of chemistry and organic chemistry in the syllabus. They will also witness some essential concepts such as the structure of atoms, the classification of elements, and chemical bonding. 

A detailed explanation of every topic has been provided. Various principles usually appear in the exam, such as Mendeleev’s periodic law, Pauli’s exclusion principle, and Hund’s rule of maximum multiplicity. Such complex principles are well elaborated for the student to understand better and remember. In addition, they can refer to sample question papers, revision notes, and ICSE question papers of the past year. 

The students can regularly visit the Extramarks website and check the latest update on ICSE Solutions and ISC & ICSE Syllabus.
