Hi Saumu, when we dream of school it shows our level of understanding and obedience in the realm of the spirit. So you need to think of this as spiritual schooling from God. If you fail the test that means that God has been teaching you something and you are not passing the test. So he cannot promote you in the spirit He has to let you go through this again. If you notice that you are going through the same type of test and trials in life, then this is the natural manifestation of your dreams. From the ending of the last dream it shows that you will pass the test the next time you have to go through it. Pay attention.
