Failed to Certify

Andy was up puking all night last night.  That was fun.  He didn't go to school today.  I didn't go to my work out class which is fine.  I worked on math and finished the first assigned section for the day.  Then I went to my regular afternoon class.  It was fine. When I got home I let the boys play on the computer and I decided to do a little yard work for a bit.  Then we had dinner and fhe and all the other good stuff.  At 10 PM I sat down to do the second lesson assigned for the day in math.  It is just now 1:30 in the AM.  After busting my hump trying to learn this crap over the last 3.5 hours I failed to certify.  I'm pretty much sick of this crap.  I pretty much hate this math class.  I'm pretty much done for the night.  Now I will get to try and certify on the one I can't do tonight tomorrow along with two additional sections.  On Wednesday there are three additional sections.  On Thursday there is a chapter review.  On Friday there is a chapter test and there are multiple sections of the next chapter due.  What the freaking hell?  This class is really starting to piss me off.
