### Exam Brief

Every year, Assam Board Class 11 exam is taken by Assam Higher Secondary Education Council (AHSEC). Assam’s state government oversees this education board. The AHSEC is the state’s governing body for higher secondary education. It is also responsible for developing the system of Higher Secondary Education in Assam (+2 stage). Assam Board was founded in 1984 by the Assam state government to regulate, promote, and monitor the state’s higher secondary education system.

In addition, the Assam board is in charge of organising the yearly examination each year in February and March. The board is also in charge of curating the syllabus, conducting examinations, advising, and supporting leadership activities in all Assam board accredited educational institutions. Before proceeding toward Assam Board Class 11 details, students must check the exam overview for a better understanding.

#### The Board of Secondary Education (SEBA)

The Assam Act, XXV of 1961 (Assam Secondary Education Act, 1961) established a Board of Secondary Education to supervise, regulate, and improve secondary education in Assam. The Act came into effect on January 29, 1962, issuing a notification by the government of Assam’s education department. On March 14, 1962, the board of secondary education, Assam (commonly known as SEBA) was established.

### Exam Summary

Class 11 is just one step away from completing board education and getting into the world of higher studies. Classes 11 and 12 are often considered as the foundation of future academic choices and are given immense importance. AHSEC Class 11 is also a time when most students become more concerned about their future careers and begin to plan for them, and it is also the year when the majority of students choose to specialise in one particular field.

• Due to the COVID-19 pandemic and the national lockdown, this precaution was implemented to avoid the social gathering of students and teachers in the exam centres.
• Apart from the Assam board, numerous other boards across the country have advanced students from 1st to 9th and 11th grades. However, for Class 10 and 12, marks were issued based on their performances in the internal assessments.

The Assam board has released the Class 11 results for students who have attempted the Assam board Class 11 examination. The exam took place in March, and students may now view their results online. To obtain the results, candidates must visit the Assam board’s official website.

Students can also bookmark this page to receive the most recent information and updates on the Assam board Class 11 examination and results.

To sit for the final test, a candidate must have at least 75% attendance in every course they have taken. For private students, the minimum attendance requirement is 60%.

## Study Plan to Maximise Score

### Preparation Tips

A timetable can be handy when studying for an exam. Students can follow some of the tips listed below to make the most of the material in this article.

• Make a schedule based on your Assam board Class 11 syllabus.
• The mistake that every student makes is that they focus on one problem, which wastes a lot of time because time is limited before the examination, and the student must focus on all the important themes from the syllabus.
• Do not refer to various books; instead, choose the one you were following throughout the session or consult the textbooks provided by the board.
• Get hold of the prior year’s question papers and begin answering them. It would allow you to learn more about the Assam board Class 11 exam pattern and put your knowledge to test.

## Parent Counselling

### Parent Counselling for Class 11 Assam Board

Q1. How can I assist my child in managing her time?
A.
Time management is the most challenging issue that students confront in the 11th and 12th grades; with so many things to juggle during the day, from school, homework, and exams to tuitions and extra-curricular activities, working without a structure results in chaotic and unorganised preparation. As a parent, you can assist your child in creating a helpful timetable for their days and weeks to help them make better use of their time.

Q2. How do I get rid of the music distraction my daughter has?
A.
Sahana (17), one of our students, has a habit of listening to music while studying. She was unable to concentrate effectively, which was harming her retention. Her mother changed the music to instrumental tones to help her learn more effectively. As a result, instead of fully removing something your child enjoys, you can deal with the problem by reducing the circumstance.

Q3. How can parents assist their children during exams?
A.
Make sure your children receive adequate sleep. Children must get a decent night’s sleep before their tests. Parents should double-check their children’s schedules to ensure that they have been given sufficient time for a well-deserved nap. A good night’s sleep can help to ease nerves and keep the child awake on the big day of the exam.
