CDS Preparation Tips 2020

Know the syllabus

Those aspiring to crack the CDS exam need to go through the exam syllabus. This will give them an idea about the topics to be covered for the exam. While studying according to the CDS syllabus, you should jot down all the topics they are confident about and those where they lack knowledge. Try to focus on weaker areas and cope up with them as soon as possible to avoid last-minute confusion.

Previous Year Papers and Mocks 

Solving the previous years’ CDS question papers plays an important role in exam preparation. This helps you in gaining familiarity with the type of questions asked in the exam, distribution of questions, difficulty level and marking scheme. Besides, it helps to assess the level of preparation for the exam. In doing so, you can focus on the weaker areas.

Keep the fundamentals clear

It is important to clear your basic concepts rather than cramming the formulas. Since simple questions are asked in a tricky format, be thorough with your concepts in order to understand and solve the questions.

Focus on important topics

During preparations, lay emphasis on important topics, carry maximum marks, and easier to score in.

Attempt easier questions first

You should go through all questions and try solving those questions first, which they find easy and require less time to score qualifying marks. Beware of attempting questions that you are not confident of as there is negative marking too.

Unwind before the exam

When it’s just one day left before CDS, stop bothering much about it instead of just relax. Sit for the exam with a rejuvenated mind.
