Yeah 4 is ideal, especially if you're trying to polish things off while still being a full time student. See, the thing is, During my first year of college i felt as though I wanted to get out of college ASAP. I'm the type of person who loved his high school with all his heart and grew tremendously, so when I go to this uppity place that constantly slams "Live on campus! you'll save money and have the best college experience!"(for the record, it isn't actually cheaper, if anything, it quadruples the cost for college, so i commute every day, and i pay absolutely nothing!) in your face, you'd better believe I'd be royally ticked. So i decided to attempt a perfect run, when I pick a class, I pass it and move on to the next, getting rid of as many pesky prerequisites as possible. To my credit, I did achieve that to some end, I passed a math class where only 5% of people pass and a Bio course where 60% fail. Heck, I even passed a class with an A that for the majority of the semester, I had nothing for a grade! But this took a massive toll on me, as juggling that much at one time is intensely stressful. I worked so hard that i felt guilty that I took a 20 minute break. So after 2 semesters of 5 classloads, i'm taking it easier on myself, and just going for some low hanging fruit for now.
Well, since it's been so long i remember very little about how to do it. It wasn't necessarily to teach you everything you had to do, a lot of it mainly had to do with moving logs from one place to another, or deforestate knot weed (a highly invasive plant that is similar to bamboo) and throw it in with the goats or chickens so they destroy it. But it was fun, the area it was in had a few stone ruins scattered around, which only added to the atmosphere.
8 hours, ouch. My heart goes out to you little lady I doubt even I could handle that. Hopefully it isn't too hot for you on those days, last thing you need is the weather against you.
