There is a 3 years work experience = 1 year of degree study rule. You can probably use your experience (3.3 years of a degree) + actual degree to qualify.
That's right, for H-1B purposes, you can qualify based on a combination of education and experience (or even just experience) evaluated to be the equivalent of a 4-year U.S. bachelor's degree (in a field related to the H-1B job). There also are a limited number of TN occupations where a bachelor's degree isn't required or an unrelated degree can work.
