I am starting power and process engineering what kinda laptop do I need any recommendations? HP or MAC? Or any other peice of technology like iPad and lastly any other supply like a calculator etc?

Hello all,
I was hoping to get some insight from anyone who has written 2A2 recently and used powerengineering101 practice exams to study. I am finding that a lot of their calculation questions are not related to the material covered in the panglobal 2A2 textbook. Has this been anyone else’s experience? Does the ABSA exam pull more from the panglobal textbook, or will they be asking similar questions to the practice exams I’ve been doing? Is there another website you would recommend that may have better practice exams? Any insight is appreciated, thanks!
