When you were at school, did you remember how to spell using mnemonics? My most-used rhyme was "I before E, except after C" used to spell words such as brief, receive and believe.
In this aptly named book "I before e (except after c)", Judy Parkinson has assembled a vast range of mnemonics under the title of "old-school ways to remember stuff".  The book was a delight to read, reminding me of some mnemonics from my school days.  The book is organised by subject and covers spelling, dates, history, science, music and much more. Here are some of my favorites:
Spelling - How do you spell 
committee ?  Remember 
Many 
Meetings 
Take 
Time - 
Everyon'e 
Exhausted. 
Diarrhoea is another tricky word to spell -

In 
A Real 
Rush, 
Hurry or 
Else 
Accident!
Numbers. Can you remember the metric prefixes? Here is an example of using the unit of length - metre (spelt meter in the USA). Kilometre (1000m), Hectometre (100m), Decametre (10m), Metre (base), Decimetre (0.1m), Centimetre (0.01m) and Millimetre (0.001m):

Milk.  Other mnemonics are offered:

Measles.
Science - Taxonomy is the system or arranging animals into groups based on similarities of structure and origin. The classification starts with Kingdom, then continues with Phylum, Class, Order, Family, Genus, Species and Variety. This can be remembered with

Fumes 
Generating 
Sulphurous 
Vapours.
English History. From William the Conqueror to the current British moniarch, there have been eight major royal houses since 1066: Norman, Plantaganet, Lancaster, York, Tudor, Stuart, Hanover and Windsor. There are two mnemonics in popular use:

The Work Place.  This chapter offers a variety of acronyms for the workplace: KISS (

Miscellany. Do you play Snooker? Can you remember the sequence of colours in which to pot the six coloured balls after the red?  Remember the mnemonic

Before 
Potting 
Black to remember Yello, green, brown, blue, pink and black.
