I'm grateful for these online classes, but there are moments when I wish someone else would take them for me so I can focus on other tasks. You are not required to purchase textbooks. You can quickly download them and lecturers submit the course material online, which is easily available and easy to read. My professors gave me with digital versions of the textbooks, saving me from having to buy them from the store. You can also request that your teacher share the links with you so that you can use them for learning support.
