As you are attending much before you are prepared, have you done 2 minutes-drill and self test in K&B books. Just do self-test in K&B book 2-3 times, make all the programs asked in self-test even in chapters, comment in programs what you learned, write package name related to topic name such as kethysiera.innerclass, kethysiera.synchronization, kethysiera.collection.map, kethysiera.generics, kethysiera.generics.confusing, kethysiera.generics.compilerwarnings etc...., give your source filename the concept covered by that source file, such as NotifyDoesNotReleaseLock.java, TrailingSpacesAreDiscarded.java, StringBufferThreadSafeTest.java, AnonymousInnerClassCannotHaveStaticMethod.
Make lots of examples, no matter where you find that example, only thing matters that you understand the concept clearly.
