i found Dan's mock exam to be very tough ,it contains lot of Q on the topic which are not disscussed in K&B,is the real exam as tough as Dan's mock exam.
i have gone through K&B ,its Master exam and marques green's mock exam5........is it good enough to go through the exam.
Nothing is tough until u know it. Dan's exam is very good and it lets u know where u r missing in ur goal. There are various questions which will give u a borader knowledge about the concepts. Questions regarding wrapper classes and collections API makes u learn the API in detail. For eg. i would like to refer to a question which i wasnt even aware of its result:
I was amazed by the answer. i didnt know about the internal working of stringbuffer class, it made me go thru the stringbuffer code.
So, i would suggest u go thru the dan exam, may be the questions are easier in the real exam than in Dan's but it will help u gain a better understanding of various topics.
Don't get me started about those stupid light bulbs.
