When we are tested in dreams, it follows that we have similar feelings in our waking life. You may feel under pressure at work, anxious about your performance, or simply that someone is judging you. It could be that you are working towards a specific goal but feel unprepared in some way. Look to the conditions of the test for a deeper interpretation. If you are stressed and have problems either with the content or physical circumstances, this points to a lack of knowledge and confidence. You may need to put extra effort into reaching your career goals. If the exam goes well then you are ready to take the lead in some way and show those that matter how much you can achieve.
