CBSE Class 12 Commerce Mathematics Unit-Wise Allocation Of Marks : Mathematics is essential in many fields, including natural science, engineering, medicine, finance and the social sciences. Applied mathematics has led to entirely new mathematical disciplines, such as statistics and game theory. Mathematicians also engage in pure mathematics, or mathematics for its own sake, without having any application in mind. There is no clear line separating pure and applied mathematics, and practical applications for what began as pure mathematics are often discovered.

Marking Schemes of Question Papers in the subjects of English Core, Functional English, Mathematics, Economics, Business Studies, Accountancy and Entrepreneurship administered in Delhi and Outside Delhi during the 2012 main examination have been included in this document. Some tips on their usage are given below :
(a) To Teachers :
— Go through the syllabus and the weightage distribution for the subject carefully.
— Read the question paper to find out how far the question paper set subscribes to the prescribed design. Grade every question by difficulty level for students who have taken the main Board examination.
— Consult the ‘Marking Scheme’ for each question, with reference to steps into which answers and awards have been divided.
— Work out concrete suggestions for the Board.
(b) To Students :
— Study each question carefully, comprehend them and write down the main points of the answer and note down their difficulties for clarification.
— Examine a question in conjunction with the Marking Scheme and find out the proximity of the answer to that suggested in the Marking Scheme. We urge the teachers to encourage their students to make use of this publication

- CBSE Class 12 Commerce Preparation tips
Tips for preparation
- To score well in mathematics in a CBSE exam, it is very important to complete your NCERT book. Almost the entire paper revolves around the concepts given in your NCERT book.
- Move to a reference book only if and when you are through with each and every question and you know each and every question (both, solved and unsolved) by-heart, given in your NCERT book. To ace the CBSE mathematics exam, you need to know the NCERT book really well.
- Some formulas are very general and require you to identify the parts in the problem that correspond to parts in the formula. If you don’t understand how the formula works and the principle behind it, it can often be very difficult to use the formula.For example, while performing integration, it is not difficult to memorize the formula for integration by parts, however, if you don’t understand how to use this formula, you will find the memorized formula of no use.
- Some formulas have certain rules that you need to follow, in order to correctly use them. For instance, in order to use the quadratic formula, you must change the equation to standard quadratic form first.
- Make a sheet of important concepts/formulas. Make sure you know these formulas and more importantly, their usage.
- For a problem based question, Read the problem to get an idea of what you’re being asked to do. Write down what you are given and what you need to find. Work with the things given in a systematic way and try to find what is asked.
- Solve all the miscellaneous solved and unsolved questions too. Solve the Sample Papers available on CBSE website.
