Imagine having this calculator for 19 years, then finding it in a lost corner of the house, with no an instructional guidebook. Hair is getting thin from constant head and scalp abuse.My wife says, sure you save everything else.It will Show in the most unlikely place.

(math 101) etc... being the most elementry to the Diff EQ ? Qualifications which are almost as outdated now as the sliderules. O'levels (ordinary level) were taken at age 16 - and one would take a whole bunch ranging from physics to music, french to woodwork, english lit to philosphy (I ended up with 13); and were used, amongst other things, to filter access to last two years of school education (what we called the sixth form). A'levels (advanced level) were much more specialised and taken at 18, one would generally take three or four; these were used to filter entrance to university. Graded between A-E (and U for terrible), A-C were passes at O'level, A-E at A'level. other wierder ones were AO (alternative ordinary - often maths) and S (special). Its all changed now. Someone with kids of right age can explain further
