The only reason for failure at school is if adequate time isn’t put into studying. Studying at school is part of the activities  that every “good” student should invest in. If you look back at how you were able to journey up to a higher institution you will see how that study plays a significant role in the academic process.

The journey to excellence is never sugary, it requires dogged attributes to consistently pass every given test or assignment.

The beautiful part of the whole thing is the joy of actually excelling as a student. Excelling comes with a sense of pride and high esteem connected to the hopes of a better outcome at the end of the academic period.

There are 5 main reasons why students keep failing at school

1. Inability to Endure Tough Times: Tough times are the periods you have to stay up at night to study, these are times you stay away from friends, family members, social gatherings and other pleasures of life only to be at the library.
2. Impatience: Students who are impatient to sit at a place over a long period of time to study would end up failing woefully as it is in many proven cases in our higher institutions today.
3. Bad Friends: Keeping bad friends would only keep you at a point for a long time. Progress is when you consistently pass an exam as a result of hard work, not shortcuts. Only the bad ones will tell you to go clubbing rather than study for exams, they will always be willing to guide you on how to sort courses but never to help you with past questions. You should run away from people with this character.
4. Poor Background: Students who never had a solid academic background, particularly from their parents or guardians might end up failing in school, Some parents find it uninteresting to encourage their kids to do assignments, they would rather take their kids out for a video game or excursion. When a child grows up with despair about studying over time it appears a burden to even attend a class and talk less of sitting in a library for hours studying.
5. Slow Learning Pace: Many students who fail today have the problem of learning quickly, While I don’t see this as a problem (since everyone’s learning pace differs), such students should look out for a mentor or coach to help develop and master the reading technique to understand a topic fast at any level.
6. Laziness: Laziness is the height of it all, you cannot successfully outdo your past results when you’re bent on being lazy. Nobody was born lazy, it’s only a choice which you can change today provided you are willing.
7. Disobedience to School Rules: Rules are rules, that must be followed strictly by the lecturer’s instruction to excel in class. When a lecturer tells you to read a material five times, there’s a reason for that, if you are told to submit a term paper at 12 noon, don’t ignore the instruction. If you are told to attend all lectures make sure you try to obey, if you are instructed not to submit plagiarized research papers make sure to obey. School rules should be taken seriously.  
8. Shortcuts: There are no shortcuts to success, the only road to passing convincingly without regrets or blame is by studying hard long before exams to master your courses or subjects.
9. Parental Failures: A parent owes the children a responsibility to investigate their rate of academic success or failure, this is done most times by visiting the children’s high school to inquire periodically how they performed. Another way is to request their results or visit the school result portals themselves to ascertain what scores their children had every semester.
10. Super Ego: It takes humility to study, its pride to ignore your lesson notes while in college, it even becomes worse when classes are missed frequently without justification.
