Hi Esther,
its better to realize now than in the exam that there are some gaps. I am sure: you will pass.
Try that:
- write a lot of example code -- many small (abt 10 lines) programs, at least one per page of the study book
-
test all combinations of types, modifiers etc. of a code example until you see the principle behind
- ask yourself wired questions about your code examples
- repeat the summaries in the book evry week and explain yourself what the content was
- write summaries of topics you find difficult
- read the javaranch
SCJP thread, ask questions, answer questions
- look for somebody to learn together, discuss, teach and test each other
