dat bootcamp generators to build your skills. im my humble opinion, you will need a little more time than three weeks. i think pat is all about comfortability and that comes through a lot of practice. I used dat bootcamp and crack dat pat and took a total of 32 pat exams before the real thing. this was probably overkill but by doing pat that many times it made the real thing relatively stress free. I dont regret the extra time i spent on pat or pushing my exam back 2 weeks
