Answer 71

well thats nice of you! like i have sooooo much to do because it's the end of the semester! i just want the semester to end already!

Answer 72

Which Semester are you in 1 or 2? I'm in semester 2 of Physics. Actually getting ready to do the Chapter test for the last chapter an then all I have left is the Semester exam

Answer 73

right now its the end of the 1st semester. the 2nd semester starts on the 18th

Answer 74

Oh well um. You can move at your own pace in FLVS and so I've already finished semester 1 (I did that before Christmas)

Answer 75

And thankfully there are only 3 chapter in semester 1 and 4 chapters in semester 2 so it's not that hard really

Answer 76

wow that sounds much easier because here we don't move on our own pace and we have like 8 or 9 chapters per semester

Answer 77

Yeah, you see the entire reason that I started homeschooling was because I had to do extra homework because SOMEONE ELSE didn't understand. Gosh I hated have to do more work cause of someone else. Not that it's their fault that they don't understand but I just think that it's unfair to give the kids that know the stuff extra work as well.

Answer 78

yeah that isn't fair and i started homeschooling because the schools here are really bad

Answer 79

Oh that sucks

Answer 80

Hey I got to go take my chapter 7 test for Physics. I'm not logging out in case I need to ask a question but I'm gonna be technically off for a bit okay.

Answer 81

okay :)
