You know that today the competition is very tough. Without good preparation, one cannot get through it. Don't worry, have faith, and you will surely succeed in the next exams. I suggest you read the following books for general awareness:
- Tata McGraw Hill General Studies Guide
- Chronicle Magazines for Current Affairs
- Latest Economic Survey
For Quantitative Aptitude, I recommend R.S. Agarwal and Kundan's book. For Verbal Reasoning, R.S. Agarwal is a good choice. Additionally, for Advanced Data Interpretation, R.S. Agarwal's book is recommended.
Furthermore, on HR-related material, review the books you have already studied during your course. Moreover, you may also seek help from CITEHR for your queries.
Regards.
