do not
besides the very good Qbank questions, a lot is wrong with this exam prep. Find capable people to explain to people the material, the guys on this videos are a total joke, professor cannot make a full sentence without saying ''euuhhh...'' , ''no sorry'', more ''eueeuuuhhh heh heh" . a lot of questions have mistakes but can't report it and comment to flag it. will definitely go with MM.
