If I have two URL's where the only difference is the case of the query string:
http://example.com?param=TEST
http://example.com?param=test
Are they both considered equal by search engines? I know the rest of the URL is case sensitive but I want to confirm that this is also true of the query string.
URLs that differ in case in the query string are different URLs to search engines. They are not considered equal and would need canonical tags or redirects to tell search engines which you prefer.
Different parts of the URL are different in terms of case sensitivity:
http) -- case insensitiveexample.com) -- case insensitive/folder/document.html) -- case sensitive?foo=bar&fuzz=bat) -- case sensitive
%7e and %7E are equivalent. The preferred form is uppercase. All of the rules on what is or is not case-sensitive are in RFC 3986.

Yes, all parts of URL after the domain name are case sensitive.
Also, query string case is important not just for search engines but it may be important for your server as well.
