After two weeks' study, I passed SCJP with a 81% yesterday. Although the score is so so, I am still very lucky because I found 7 errors when I reviewed the question. I am not satisfied with the performance in Flow control and declaration. I only got 66% for each. Kathy's book and Javaranch gave me a lot of help. Dan's Question is also a great help and interesting. Thanks for everybody's helping me!
