Tut102 indicates that it will only be in the 2011 Jan/Feb exam...but then again you never know. On a related topic, does anybody know for sure if the iSQL*Plus stuff be in the exam? Tut102 (the other one) mentions that it is only in the books because it is used in some Oracle cert course.
I'm with @Mota with this. I know they said we don't need to study it, but I'm at the very least reading through the stuff so I'd have a chance if they do ask questions (wouldn't be the first time). As for the iSQL *Plus stuff, I think the only thing they may ask is with the substitution variable. Other than that, I don't think so.
