I predict that in three weeks:

• we will be just as tired
• we will have gotten through it - but maybe not together
• we will regret not doing that crazy last-minute mugfest (ie now)
• we will not be doing all the things we wanted to do
• we will be just as clueful or clueless about college
• we will worry about what to wear for prom
• we will be sad that it’s almost all over already
• we will visit the sea together
• we will.

For those who are still stumped by the Math HL Prelim 2010 P2 Q3 involving P( |X-2| > a ) = 0.25 it’s somewhat related to Math HL Prelim 2008 P3 Q5iii that I mentioned a few months back about the use of Solver, and can be handled similarly without having to think (ahem) about the bounds being x standard deviations away from the mean and hence assume that it’s negligible.

I guess this specific concept is actually in HL Core Statistics; the earlier parts of the 2008 question were decidedly not so that entire question was placed in P3.
