Please see section 5 of the exam objectives of more information on the use of operators. Most everyone feels that my single topic exams on the operator topics are difficult relative to the real exam. If you want to avoid doing extra work then you certainly won't want to try the exam marked optional. Please keep in mind that your score on my exam will probably be a lot lower than your score on the real exam so please just use it as a learning experience. Don't try to use it as a tool for predicting your score on the real exam. My questions involving bit manipulation frequently use hexadecimal. If you need extra help in that area then please see my tutorials page. Another great resource for help with bits is Cat and Mouse Game with Bits here at the ranch. I hope that Bert might provide further insight concerning what might be emphasized on the real exam.
