Preparation Strategy for ICAR AIEEA 2025

Make a schedule:

To get ready for the test, you need to make a suitable study plan. To ensure adequate preparation, a schedule is necessary. Anyone can easily arrange their available time on paper. The executive must have a great deal of willpower and determination to accomplish this. Any successful person would therefore have a schedule that made it possible for them to achieve their goals.

Mapping Concepts:

One of the most effective learning strategies is concept mapping. The concept mapping technique has been shown to be an extremely successful study method that helps students develop logical thought patterns.

Take frequent short breaks:

For extended periods of study, brief breaks are crucial. Taking breaks between study sessions is crucial for you. Results from extended study sessions without a break may be ineffective. You must incorporate short breaks into your study plan.

Prepare Brief Notes:

It is critical for you to prepare short notes or important points while revising the concepts. Writing down key points and going over them will help you to better retain the knowledge obtained from the subject.

Take good care of yourself:

The majority of students experience stress during exam time. Stress is unavoidable during the preparation journey. So, it is important to get enough rest during the preparation period. It is important to remember that you must follow a healthy diet to retain energy.
