💡 Pro Tip
Don’t use AI simply to generate answers and submit them. Ask it to explain concepts, create practice questions, identify weaknesses, or review your work. This keeps AI in the role of a learning assistant rather than replacing your own thinking.
Free vs. Paid AI Tools
Free plans are usually enough for occasional studying, basic writing, research, and simple projects.
Paid plans become more useful when you use AI daily, work with larger files, need advanced features, or require higher usage limits.
For most students, starting with free plans and upgrading only when necessary is the most practical approach.
