Today (exactly 4 weeks after taking the exam and submitting the code), I got the confirmation about passing the SCJD exam.
This is pretty much my first post to this list, I did not have to ask anything, since all information I needed was already here.
I needed ~3 months for completing the assignment. (I used a very minimalistic approach, implemented the must features only).
I would like to thank you for this great list and the many helpful posts. Also big thanks to Andrew for his great book.
