I revised and supplemented my strategy guide with some additional advanced concepts and examples, and it is now 14 pages long, so the price is now $25. If you already bought an old edition and want the newest one, you will not be charged the full $25 but only the $5 difference. Please email me using the same email address you used to buy the earlier edition. Existing students will get the new edition at no cost.
As before, Paypal payment to
ichispiro@gmail.com and provide your email address. Thank you!
