Just failed the FE chemical exam and my resource was PPI. Unfortunately, it lacks an important section which is Material/Energy Balance (You have to look for another source because they just simply replaced it with the separation section). Also, some other materials were totally different than the actual covered material in the FE (Solids handling, Safety and Ethics.).-The Q-bank generates many irrelevant and lengthy questions in comparison to the actual questions in the exam.-Their services are overpriced.To be fair the other materials were well covered in PPI and did good in them
