I wanted to take the CSWP exam so I did the sample question. I made the part and everything seems correct to me however I couldn't get the correct answers. I even redo it a few times and tried something different each time trying to find what I did wrong but still didn't work.. I noticed that even when I got the answer right for question 1, but when I modified the equations for the next question, the answer was wrong. I tried changing the equations back for question 1, the answer is different from the first time... please helpp!!!!!
