I want to let you know that you're my favourite subject. That's why I find it so sad that you don't know the difference between 'there' and 'their'. Shouldn't a learned individual like yourself be a little more careful? Do you need a beta? I'm happy to help.
Also, peas ants, back wards and mea sure are not acceptable representations of those words. If you're feeling a little trigger happy, maybe you should take your thumb off the space bar for a bit. Sentences that stop halfway through are not complete thoughts. They should also end in periods, exclamation marks or question marks. Quotation marks come in pairs and should be put at the front and back of a quotation.
When referencing p. 170, please ensure there is a p. 170 in the book. It is hard to critique a poem that is not there, especially when you are asking about its views of imperialism, a subject you have not yet taught. It is also prudent to make sure when you say 'see map on next page', there is, in fact, a map on the next page.
Perhaps you could ask Units 3 and 4 to take a look at Units 1 and 2, which were coherent, to the point and easy to understand. Your wandering narrative in the former units is extremely confusing. It is wrong that I prefer to look up the subject on wikipedia rather than attempt to wade through your babble for the answers.
You are lucky I have experience with wayward correspondence courses. I have honed my skills on a Philosophy course that was even worse than you. Still, I expect some standards among my favourite subjects. I'm putting you on notice: be more awesome.
