which books are best for cds and afcat?

Apoorva Student Expert 10th Nov, 2019

Hello dear student,

I would suggest you to buy a general knowledge book which is that will help you with the GK questions. And then you should buy a book of reasoning and aptitude pictures that will help you to improve your aptitude questions. Why you asking for a book then I would like to recommend you pathfinder CDS it is one of the best books you can and have for the preparation. While for afcat you can buy Aarihant's afcat book for preparation. I hope this was helpful to you.

Sir......i dont have a score of 60 for my +2 math.....will i be able to give cdse......being a female...

Papeya Dubey Student Expert 23rd Oct, 2019


When it comes to CDS Exam, girls are only eligible for OTA  with age limit being 20-24 years and eligibility criteria being having passed Bachelor's Degree in any discipline from a recognized university.

So, you just needs to be a graduate, there's no such specific mention of having math or scoring a certain marks or percentage regarding this matter. This mandatory of having Maths and Physics applies only in case of AFA.
