    A major source of teen stress is school exams, and test anxiety is not uncommon. When you recognize

your teen is under stress, how can parents help your teen stay calm before an exam?   

    Be involved. Parents need to be involved in their teen's work.    1    What they look for is your patience-

to talk, to cry, or simply to sit with them quietly. Communicate openly with your teen. Encourage your teen

to express her worries and fears, but don't let them focus on those fears.   

    Help them get organized.    2   Together, you and your teen can work out a timetable in which she can

study for what she knows will be on the test.   

    Provide a calm setting. Help your teen set up a quiet place to study and protect her privacy. Give them a

nutritious diet. It is important for your teen to eat a healthy, balanced diet during exam times to focus and do

her best.    3    If this happens, encourage your teen to eat light meals or sandwiches.    

       4    Persuade your teenager to get some sleep and/or do something active when she needs a real break

from studying. Help your teen balance her time so that she will feel comfortable taking time out from studying

to spend time with friends or rest.   

    Show a positive attitude.    5    Your panic, anxiety and blame contribute to your teen's pressure. Make

your teen feel accepted and valued for her efforts. Most importantly, reassure your teen that things will be all

right, no matter what the results are.
