    Best Preparation Strategies for Mathematics class 11

    All the students who have mathematics as their subject in the 10+2 must make sure that they carefully deal with subject so as not to mess with the same. Mathematics can be dealt only with lots of practice paving its way. The more one practices mathematics, the more one gains more knowledge about each and every concept.

    1. Allocation of Adequate Time: Manage time for all the topics separately. Once you are introduced to each and every concept of the subject, you get the urge of practicing them to get your concepts clarified about all the tough as well as easy sums.
    2. Relevance of a Study Plan: All the students appearing in the science or commerce stream are expected to prepare a study plan or chart after referring the date sheet and curriculum. After the same they can make notes according to their own convenience and choice so that their studying and revising becomes way easier at the end of the examination preparation tenure.
    3. Building of Patience: Mathematics is completely based upon patient practice. The students must carry on their continuous practice regarding the subject so that they do not fail to skip off understanding of any of the concepts at any cost that was taught in school.
    4. Confidence is the Key: The students who are going to appear in the class 12 board examinations must make sure that they have faith in themselves. Confidence and determination makes things easier and one begins to challenge oneself regarding the completion of the same.
    5. Dedicate Study Time: The board applicants are required to dedicate at least 2-3 hours every day to the practicing purpose of the subject. Mathematics expects attention and thus, the same works the best in solving easy to the most miscellaneous sums in all the chapters.
    6. Refer to the Answer Key/ Solution: It is not possible for the school teachers to solve each and every sum at once, contained in all the chapters present in the book. This is the time when the solutions of the same published make sense.
    7. Practice Sample Question Papers of Previous Years: Solving more and more previous year sample question papers for the several subjects occurring by the board authorities for 10+2 assists the students largely. Practicing the sums from the previous five to ten years question papers of the subjects targeted helps the students to grab idea on the typology of the questions occurring, Not only this, but the students also get an idea of the pattern of the questions and also the marking scheme designed for both short and long answered questions.
    8. Refer to the Best Publications in Consultation with Experts: Good references are a must for good guidance of the board applicants. If one chooses the best publication books, then it is possible that they get an access to the best guidance for the lessons that they are approaching.
    9. Take Advices from Qualified: The boards applicants are expected to take advices form their seniors who have already passed or qualified the exams, their parents, their peers as well as subject teachers who can explain them the whole process of studying. Not only will they suggest books that would help them but also ways to prepare for the examinations.
