Smart CDS Preparation Strategy for 2026

The process of getting to your goal with CDS is not about how much you study but about what you study and how.

The following is a proven CDS preparation strategy used by the Trishul Defence Academy’s Successful CDS Candidates:

• Start with the CDS Syllabus

The first step to success is analysing the entire CDS syllabus and dividing it into the areas in which you are strong, average and weak.

• Make a Realistic Study Plan

Create an achievable daily schedule based on how many subjects you actually study each day and how much time you will devote to each subject based on its importance. A balance should be achieved between subjects that do not change (static) and the news/current affairs.

• Practice with Previous Year Papers

This will help you understand the trends of the questions and will get you acquainted with the CDS syllabus pattern.

• Focus on Accuracy

When you are frustrated with trying to answer questions or answer them incorrectly, it can hurt your final score. Mock tests can be utilised to assist you in developing your accuracy.

• Prepare for SSB Alongside

The written exam allows you to qualify; the SSB (Services Selection Board) interview evaluates your potential. You must develop yourself personally during this process. The integrated approach outlined above will ensure you have a strong foundation for successful CDS exam preparation 2026.
