- The first and foremost tip for the student is to prepare a study routine. Students are advised to make their own timetable and devote considerable time to all the subjects. A uniform routine will help the students pay equal attention to all the subjects and the topics of the Arunachal Pradesh Board 11th syllabus 2023.
- Students must go through the entire syllabus carefully before starting to study for the Arunachal Pradesh Board 11th 2023. Thorough knowledge of the syllabus will help the students to understand all the topics included in the exam and schedule the study preparations accordingly. Students will also have an idea of the weightage of each topic and study each topic in order of its importance.
- All the students must have an idea of the best books for the exam so that they can cover each topic in a detailed manner. Students are advised to study all the topics from the school books before moving on to the reference books.
- Every student must follow a healthy routine before and during the exams.It is necessary to engage in activities that will reduce the stress level and keep the students mentally positive.
- Students must make notes of the formulas, equations and difficult sections of each topic. After completing each chapter they must solve all the questions related to the chapter. It is mandatory to solve sample test papers of all the subjects to self evaluate and work on the mistakes.
