Curriculum Block for QT Essentials
-
bq. Or you are too lazy to learn?
This condescending tone is uncalled for. Mr.Universe was asking a very specific and reasonable question, as the old certification curriculum pages that were posted on the qt.nokia.com site are no longer available. I had tried, myself, to search for them to offer up a cached version to him, but had no luck.
-
Sorry, was thinking you are looking for old examples from peoples who has already done this exam. Just for study this pages and got through exam like peoples do with CCNA exams. My bad. Don't be angry to me :)
-
thanks mlong,
I also tried to get the pages via google cache or archive.org, but couldn't find it.
The thread you posted isn't exactly what I was looking for, but it looks like a suitable alternative...
Can you tell me wether the links posted there by Rahul Das cover all topics that are part of the essentials-exam? (From my memory I'd guess they do) -
Hi Mr. Universe,
There are even more threads with topics, like "this one":http://qt-project.org/forums/viewthread/20507/
Aditionally, here is the link to the "certification page":http://qt.digia.com/product/learning/certification/ . Currently it only says: we are collecting data and will post it soon....
-
Mr.Universe,
Those topics, as I recall, seem to be pretty comprehensive. The most important part, though, is that you're already comfortable with Qt development in general. The purpose of certification is to indicate that you're genuinely knowledgeable in the area, so just make sure that you're comfortable with those general types of topics. If you're comfortable with the given topics in that list, then you've probably done enough development with Qt to handle any other related topics which may or may not be listed there.
-
Thanks mlong,
I guess you're right. I am working with Qt every day in my job, so I'm sure I can answer most of the questions without problems, but I remember some topics in the curriculum I never came in touch with during my work... But from my memory I think the list in the other thread covers those topics...
I also sent an e-mail to digia, if they can send me a copy of the old page, if they do, I'll post it here, if not, I'll probably pass the exam anyway! -
