So I failed CSWP Segment 1 today! I feel a bit disappointed and I have decided to buy a book that has much practice problems for modeling as I have done what is available online for free. But before I go ahead and pick a random book, I was wondering if anyone can recommend a book with lots of practice problems (harder ones). I don't need a book that teaches Solidworks as I am familiar with techniques. I just need much more practice to get fast enough for the test.
