What I (R. Craigen) know about the prehistory of mathletics at U of M (not much -- if you know more send me a note!):

• 1938:  Dr. Nathan Mendelsohn, a longtime member and multi-year head of our department who recently passed away, was part of the (U. Toronto) team which won the very first Putnam competition many years ago and for decades served on the problems selection committee for the Putnam exam.
  
• 1958 (Spring): UM team (Ian Connell, Wilbur Jonsson, Philip "Jim" Peebles) ranked 4th -- our highest ranking to date.
• 1961: Barry Wolk was a Putnam Fellow while  enrolled here in 1961 (unofficially we know his score was highest, although this information is not publicly released with the rankings -- Putnam Fellows are listed in no particular order).  Barry still is occasionally seen in our sessions to share his expertise with the latest crop of aspiring Putnam Fellows.
• UM is one of 42 universities to have ranked in the top 5 at some point.
  
• 1973: Dr. Tom Kucera (an undergraduate student at the University of Manitoba at the time), received an individual Honourable Mention

When I arrived in 1999 U of M students had not participated in Mathletics for a few years (nobody has ever clarified how many).

CONTEXT OF RANKINGS: 
-    Generally there are about 400-500 institutions competing in the Putnam, so top 100 ranking ≈ top 20%. 
-    "N/A" generally means one or more of the 3 students preselected for our Putnam team obtained a score of 0. 
       Other team members and students we hadn't selected for the team may still have done quite well.
-    There are about 4000 individual participants in the Putnam exam, so a rank in the first 1000 means top 25% (out of an already select group!). 
-    70-100 teams participate each year in the NCS/MAA contest.

SOME THINGS YOU SHOULD KNOW

First, never memorize a mathematical tool without:

• being prepared to prove it on demand or else knowing for sure that it is well-known but difficult to prove in an elementary fashion
• learning how it can be exploited and how to recognize places where it might apply (i.e., by solving hard problems with it)

Second, practice!  A "natural" problem solver will do moderately well without much preparation, but nobody will distinguish themselves without preparing and working on problems for months in advance to become familiar with problem types and tools, and to keep one's brain "in the groove".  At our practice sessions we provide tools and experiences that have proven to be most effective in preparation.  A musician may be good but cannot play the sonata without many hours of scales and arpeggios; an athlete may be a backyard jock but won't shine in varsity athletics without running drills all season with their teammates.  In the same way a mathlete may be naturally "good" but will not distinguish themselves without deliberately laying a foundation of basics and honing their skills.

Third, your brain is not separate from your body.  Eat well; get plenty of sleep -- especially before competitions -- and exercise; manage the stress in your life; maintain a positive attitude, approach each question with confidence, and enjoy your mathletics activities.

Fourth, don't get discouraged; don't give up.  While math per se isn't as hard as it's reputed to be, the competition questions you will face at this level include some which are selected to be deucedly difficult.  You shouldn't have overly high expectations for yourself; there is no shame in not solving everything (or even more than a few problems!).  Take every small victory as a sign of progress and don't beat up on yourself.   We tell people to try to solve everything but realistically most students will get 0 on the Putnam in their first year  And frankly, those of us coaching can't solve everything in these contests -- you must gauge your success relatively.  ANY success is praiseworthy.  Getting 0 is nothing to be ashamed about, and really means nothing -- the best sometimes draw a blank in this activity.  But getting a decent score from time to time, that MEANS SOMETHING; that won't happen by accident.  When you fail, get up again, dust yourself off, and try another one.  When stuck on a problem don't get into a negative mental spiral, but keep attacking the problem from every angle you can think of.  As you'll eventually learn most contest problems have a "secret door" and once you find it, you will find the problem (relatively) easy.  They are designed to discourage you initially.  Don't let that happen!

Some outside links to fundamental tools (come to the weekly practise for help with these and much more!)

Jensen's Inequality  (NOTE:  Possibly the most powerful and versatile inequality. Learn to master all the ideas in it:  convexity, means, etc.)
Pick's Theorem   (A crazy fact about polygons with vertices on the integer lattice.  It is subtlely behind many contest problems -- learn to recognize it even when it is masked)
Cauchy-Schwartz Inequality  (Absolutely fundamental)
AM-GM inequality (You can't get along in contests without at least this.)
Inclusion-Exclusion
Fermat's Little Theorem (and Gauss' Generalization)
Modular arithmetic and various standard tricks with it
Viete's relations (between the roots of a polynomial and its coefficients) -- and how they are exploited
The pigeonhole principle  (Simple yet versatile.  More profound than it sounds at first)
Power of an inside/outside point  (Makes light work of many geometry problems!)
Heron's formula for the area of a triangle  (An old formula for the area of a triangle; a good thing to know for triangle problems)
Basic properties of matrix determinants  (Knowing some of these solves nasty-looking problems with a light touch).
