A weak 5th house causes academic difficulties.
A weak 5th house means that the lord of the 5th house i.e., the planet representing 5th house is weak in your birth chart.
It means that it may lie in a deliberated sign, or is damaged due to it acquiring the 6th, 8th or the 12th house, or it may be unfavourable for you.
As the 5th house represents children, academics, mentors, you may have a problem related to these elements of your life.
