As a student I'll do just about anything to be able to do well on tests, homework projects, and of course the dreaded pop quizzes. Over my college "career", as well as in high school, I've used quite a few different sites to help me out, some of which have been more useful than others. One site that I just used last semester was Course Hero. In one of my engineering classes I had a project that had to do with balancing a specific 6 cylinder engine and as a group we couldn't figure out how to do it, at all. Looking through the book we saw a few similar engines that would be very helpful, but the book (it was a horrible textbook) didn't have any solutions. So using google we looked everywhere to see if we could find the solution manual, or even just solutions to similar problems and had zero luck, until we saw CourseHero.
CourseHero markets itself as a place that "provides students with course-specific study documents, homework help, and flashcards to help them learn more effectively". While you can search documents and see what they have available, to actually unlock a document (and see more than the first page) you're pretty much going to have to pay. They do have an option to upload documents in exchange for unlocks but for 10 uploads you only get two unlocks, and these uploads aren't as easy as you think.
Originally I had uploaded about 10 sets of homework I'd completed for a materials class with both the questions and answers (each one was between four and five pages) and each one was rejected. Now by rejected I meant they didn't count towards the "10 uploads for two free unlocks deal" but they still took those documents and uploaded them to their site to get other people to pay for them. I tried uploading notes, quizzes and powerpoint as well, and the only document they ended up giving me credit were my lab reports. Very misleading if you ask me.
Because we knew we wouldn't be able to get enough documents uploaded it was decided to go ahead and buy a month, which was $39.95 for one month. Now it is cheaper if you do quarterly or annually, but you have to pay for a full year and obviously you won't be needing it in the summer or over winter break so you kind of counter act that by paying when you're not using. Even when you have a membership you don't get unlimited unlocks, and are capped at 30 per month, however this would probably be plenty. You also get "tutor credits" but I found that whole area of the site to be super confusing and didn't use any of it in my month.
While the solution manual ended up being very helpful for my engine balancing project, I then tried to use Course Hero again for a final lab report for another engineering class. Looking through their documents (selecting both physics and a few different engineering majors) I got a lot of unrelated results but finally found three that looked like to be similar, just based off what I could see from the first page. Which for how much lab reports are formatted doesn't actually give you very much information. Two of those three ended up being off the wall biology papers (maybe for a freshman orientation class?) and the third one was exactly what I was looking for, until I actually looked at it. The report was dead wrong on half of it's conclusions and all of it's calculations. I'd say the best grade it could have gotten was a D+ .
Overall: I don't think Course Hero is worth the money unless you know there is something on their site you need and don't have another way to get it. They don't have that many solution manuals or study resources, and with only 30 unlocks a month you can't just get everything and hope one of the items is actually what you need. I'm a much bigger fan of Chegg (although it has it's problems too), and am so glad I didn't get the full year of Course Here.
Oh and those about 15 unlocks I didn't use while I had my month subscription (you have to make sure to cancel because they will auto renew and charge you if you don't) they took all of them and the homework help credits back at the end of them month. Something I think is pretty deceptive since I paid for 30 unlocks.
Pros - Might have the information you need
Cons - Expensive, Incorrect information, limited access per month, and way more...
So here's my very long Course Hero review. Do you use any study sites?
