Hi there,
Congratulations on your upcoming college journey! It's great that you're looking to get ahead and learn some calculus before starting your classes. Here are a few suggestions for learning calculus on your own:
1. Utilize online resources: There are many websites and online courses that offer free tutorials and lessons on calculus. Some popular ones include Khan Academy, Coursera, and edX. These sites offer video lectures, practice problems, and even quizzes to help you learn at your own pace.
2. Use textbooks and study guides: As you mentioned, borrowing a textbook from a friend is a great way to get started. You can also purchase a calculus textbook or study guide to have as a reference. Make sure to choose one that is recommended by your college or that aligns with your specific course syllabus.
3. Practice, practice, practice: Calculus is a subject that requires a lot of practice to fully understand. Make sure to work through as many problems as you can, and don't be afraid to ask for help if you get stuck. You can also find practice problems and solutions online or in your textbook.
4. Join a study group or find a tutor: Sometimes, having a study partner or a tutor can make a big difference in understanding a difficult subject like calculus. Consider joining a study group with other students who are also learning calculus or reach out to your college's tutoring center for help.
Remember, learning calculus on your own may not be easy, but with dedication and hard work, you can definitely succeed. Good luck!
