Hii Pandey,

Arihant Biology books are good interms of Content.But the books of Arihant have more mistakes and errors.It is good gor solving MCQ's .But rather than Arihant ,MTG books are better compared to quality.If you are taking up NEET exam or AIIMS first of all prepare NCERT text book and then go for MTG book rather than Arihant .

Thank you.
