Books:
Anna university all semester examination books and study material can be accessed through below link. Feel free search for different subject books and authors. The link will provide both local and foreign author books for references. Share the page with friends and college students as required.
GATE:
GATE papers can be a good practice for any competitive technical exams like DRDO, ISRO, REC, BEL, BHEL, GAIL, ONGC, IOC, NTPC, NHPC etc. As candidates we can prepare for GATE exams and try solving the papers for getting good score in other entrance examinations.
