Preparing for the mathematics board exams in Class 12 humanities requires a systematic and focused approach. Here are some effective strategies to help you excel in your preparations:

Understand the Syllabus:
- Start by thoroughly understanding the syllabus. Class 12 mathematics for humanities typically includes topics such as Relations and Functions, Calculus, Linear Programming, Probability, etc.
- Make a list of all the chapters and subtopics to have a clear overview of what needs to be covered.

Create a Study Plan:
- Design a study plan that allows you to allocate sufficient time to each chapter.
- Break down the topics into smaller sections and allocate specific time slots for studying each section.
- Try to cover the entire syllabus at least a month before the exams, leaving ample time for revision.

Study Materials:
- Gather all the necessary study materials, including textbooks, reference books, and previous years' question papers.
- Make use of reliable online resources like EduRev for additional study materials, practice questions, and mock tests.

Conceptual Understanding:
- Focus on understanding the underlying concepts of each topic, rather than rote memorization.
- Read the theory and explanations carefully, and try to relate the concepts to real-life examples.
- If you encounter any difficulties, refer to your textbooks or online resources for further clarification.

Practice Regularly:
- Mathematics requires regular practice to excel. Allocate a significant portion of your study time for solving practice questions.
- Start with basic questions and gradually move on to more challenging ones.
- Solve previous years' question papers to get a feel for the exam pattern and to identify the important topics.

Revise and Review:
- Regular revision is crucial to retain the concepts and formulas.
- Set aside dedicated time for revision, preferably on a daily or weekly basis.
- Make concise notes or flashcards of important formulas, theorems, and concepts for quick revision.

Seek Help:
- Don't hesitate to seek help from your teachers, classmates, or online forums if you encounter any difficulties.
- Discussing and solving problems together with peers can enhance your understanding and clarify any doubts.

Time Management:
- Practice time management during the exam preparation phase to simulate the actual exam conditions.
- Solve practice papers within the stipulated time to improve your speed and accuracy.
- Identify your strengths and weaknesses to prioritize your efforts.

Remember, consistent effort, regular practice, and a positive mindset are key to excelling in mathematics board exams. Stay focused, follow your study plan, and give yourself sufficient time to revise and review the topics. Good luck!
