Purdue University has an excellent page dedicated to explaining how to format various kinds of essays (i.e. MLA, APA, Chicago). Formatting papers to fit certain guidelines can honestly be the worst, however, it's important for your papers to be presented in a serious way because your writing deserves to be taken seriously.
Rewordify is a website that has a few different uses that may be useful for you! Here is a list of things it can do for you --
You can upload your writing into the yellow box, hit "Rewordify text", then click on the "stats" button at the top. This will give you lots of information about your language, what reading level it is at, sentence lengths, and much much more.
Another useful aspect of this site is locatable at the top left corner where it says "Classic Literature". Here, you can find tons texts (some of which we will be reading) and you can easily access specific chapters and sections. The website will take complicated language and simplify it for you if you are having trouble with the language.
One last thing that I like using it for is finding quotations -- rather than flipping through a book I can jump into the online text, use control + f to find specific lines, then be able to better locate the quotes in my book if I plan on using and citing them in my writing.
This YouTube channel features hundreds of short (about a minute long) videos that go from breaking down simple themes in literature to writing better theses and topic sentences. I know that oftentimes I am not in the mood to read through summaries of books or explanations on how to improve writing, and so I highly recommend this channel as a visual and audio based resource!
While this resource can get a really bad rap among teachers, it is amazing. Although Sparknotes does not serve as a replacement for doing readings, if there are circumstances in which you don't find the time (or simply forget) to do readings, please go here. Most literature we read will be thoroughly summarized and briefly analyzed here. Resources like this are great so that if we discuss text in class that you weren't able to read, you still can have enough understanding to participate which is of high importance. :)
