How to prepare for the BPSC AAO

  • Understand the syllabus and examination pattern.

It is essential to have a clear concept regarding “what to study?” & “How it will be asked?”

  • Create a study plan.

Once you have the perfect materials, you must create a study plan. This will assist you in remaining on track and making sure that you cover all of the crucial topics. Your study layout has to be realistic and achievable, and it is necessary to plan practical time for every analysis of a new topic and revise what you have already learned.

  • Self-Study or Coaching 

The most common questions in students’ minds are how to prepare for the AAO exam and whether to take coaching. The best decision will be a combination of both. Now,  AAO  is not something you have included in your school curriculum. Therefore, coaching will guide your preparation by providing relevant study materials and tests. Then, you can solve exercises and review materials to study independently.

  • Work on fundamentals 

Developing fundamental concepts should be prioritized before moving on to  AAO exam-level questions. So, focus on studying basic concepts and practice easy questions first. Then, gradually move on to higher-level questions.

  • Practice lots of questions. 

After completing a topic, practice asking as many questions as possible on that topic. Move from lower to higher-difficulty questions. Reviewing the concepts a few times through practice can help you prepare for the AAO exam.

  • Analysis of test

A practice test is a simulation of the actual test. So, as the exam approaches, taking practice tests regularly should be a part of your AAO preparation strategy. Additionally, it is equally important to analyze your simulations and identify your weaknesses.

  • Practice regularly

One of the best approaches to put together for the AAO examination is to practice answering questions regularly. You can do this by solving exercise papers and taking mock tests. Many special exercise papers and mock tests are available online and in books.

  • Stay motivated.

It is essential to be stable, active, and motivated throughout your preparation.

  • Focus on your weak areas.

As you start answering questions, you will perceive your weak areas. Once you know your weak areas, you can focus your research on these topics. You will additionally need to get additional exercise material for these topics.

  • Stay up-to-date on current affairs.

The AAO examination also asks for current affairs. Therefore, it is essential to be updated on modern events. You can use newspapers, observe information channels, and follow information websites and social media pages to be updated.
