I passed the structures exam on the second attempt.
The first time I studied with Kaplan, Ballast, and Black Spectacles, failed with level 2's in a few categories.
The second time, I bought the Thaddeus seminars and it made all the difference. Understanding the concepts and components of each equation is was key.
Thanks to everyone who posts on here - it helped me along the way (It was a long road.. 4 years).
To those still working on it - keep studying, don't give up, you'll get there!
