Hi everyone
Thank you everyone on the forums for your help in preparing for the 801 802.
In my experience the 801 was easier then the 802, for me i should have study more cmd promp commands.
But its all behind me now
, on to MCSA.
Study material was eli the computer guy and professor messer videos, Study notes from the amazing community here at tech exams and Mike Meyers book (really enjoyed how he wrote the book compared to other books i have looked through). Studied for 2 weeks, 1 week of reading mike meyers book/youtube videos and 1 week of practice tests and materials.
Also Some notes for everyone, (since the file upload does not like any of my formats and i dont want to point people out of site here they are) there are many duplicates, (helped me to type them multiple times ) Cheers everyone and goodluck!!!
