Overview:With 3 sections and 10 units, the ISC Class 12 Maths syllabus contains several important topics relevant to entrance exams after 12th too. To score 80/80 on the theory paper in the class 12th maths exam, go through the detailed syllabus overview, the weightage of each topic, and the best books.
ISC board's Maths is a little tough compared to the CBSE board. A thorough understanding of the ISC Class 12 Maths Syllabus is essential:
To create a well-structured study plan with time allotted to each section and revision.
To solve relevant topic-wise and unit-wise sample papers and practice tests.
ISC Class 12th Maths Syllabus (Unit-wise)
The Maths theory exam has a weightage of 80 marks, and 20 marks are allotted to Project Work.
The class 12 ISC Maths syllabus has three sections: A, B, and C.
Section A is compulsory for all candidates. Section A (65 marks) will consist of six questions.
You will be required to attempt all questions. The internal choice will be provided in two questions of two marks, two of four marks and two of six marks each.
You can attempt questions from either Section B or Section C. Section B / C (15 marks).

ISC Class 12 Maths Syllabus: Preparation Tips
Here are a few crucial tips and tricks that will help you prepare for your ISC Maths Board Exam:
First of all, take a thorough look at the detailed ISC Class 12 Maths Syllabus PDF and exam pattern.
Study each topic of the prescribed books.
Make sure you take notes during your study that include important points. Those notes will help during the revision period.
Strategize and prepare the long-form questions (4-6 marks), usually from the Calculus or Probability section, and try to perfect them by practising them regularly.
Try as many mock tests as you can. After completing each section, attempt the section-wise tests to evaluate your preparation.
Make sure you follow up on your study plan regularly.
