Additionally, if the user is facing financial constraints, they might reach out to local educational institutions or government departments for assistance. Some initiatives offer free textbooks to students in need. That's a good point to include.

Another thought: sometimes authors or other publishers might have open educational resources (OER) similar to the content in Deepthi's book. The user could search for OERs covering the same topics. Platforms like OpenStax or OER Commons might have free textbooks that align with the required syllabus, even if they're not from Deepthi Publications.

First, I should consider the legality of downloading textbooks for free if they're still under copyright. Even if the user's intention is good, sharing copyrighted material without permission is against the law. I need to make sure that the advice given doesn't promote piracy.
