I havn't exercised in years what will i do tomorrow for the Psyical Fitness Exam?

If the test is tomorrow you really dont have many options except failing the test. You can not expect to increase your strength in only a couple hours before your test by such a large percentage (1 pushup compared to 7). Sorry to say but it looks like you will just have to accept the "useless" gym for the next two years take your loses and move on.
