Taking Calculus 1 online is a viable option, especially if the course is accredited and your school accepts transfer credits. It's crucial to verify your institution's policies on online course credits. Many participants emphasize that the main benefit of a traditional class is access to professors and TAs for support, but self-study can also be effective if you stay disciplined and engage deeply with the material. Some individuals have successfully learned calculus online, reporting that they gained a thorough understanding by taking responsibility for their learning. Planning to complete both Calculus 1 and 2 in five months is ambitious; it may be more manageable to focus on one course at a time, particularly since Calculus 2 often builds on concepts from Calculus 1. Utilizing online resources and seeking help from knowledgeable individuals can enhance the learning experience.
