Tips to Make the Most of These Resources
- Combine different tools. Watch a Khan video on a topic, then practice similar problems on Wolfram|Alpha or Desmos.
- Ask clear questions. When using forums or tutoring (Schoolhouse, StackExchange), describe the problem and what you tried.
- Stay consistent. Set aside time each day to review calculus. Regular practice helps even the hardest concepts sink in.
- Use official materials. When possible, work from your textbook’s problems and then use these sites to check or clarify.
- Form a study group. Study with friends and use or Stack Exchange to solve homework together.
- Be patient and positive. Calculus is challenging, but with these free resources, you can learn step by step at your own pace.
Calculus may seem daunting, but you are not alone. These 10 free platforms provide video lessons, practice problems, tutoring, and tools to support your learning.
