1. They are bored and uninterested in the subjects

2. Hate the teachers

3. Hate the students

5. They could be lazy procrastinators who have found everything easy and so have forgotten how to study or don’t have the discipline required to put in the effort needed or fail due to not changing their methods

6. They stay up too late making them feel tired in the mornings and of such don’t wake or sleep in due to a multitude of reasons

7. Have an inferiority / superiority complex and so don’t like being told what to do which can lead to dropping out, getting an expulsion due to their actions against said authority figures and / or loosing interest

8. Have a plan already for after school which does not need good grades or are inheriting / taking over a company owned by their equally/less/more intelligent parent(s)

9. They could get mixed up with the wrong crowd and get hooked on drugs such as weed and alcohol essentially leading to many issues

10. Feel socially inclined to be cool or succumb to social pressure of which means getting bad grades and not doing study / homework

11. Lack in other intelligent aspects such as an adequate memory

12. Could be like ‘rain man’ and so cannot pass on all areas of school due to lack of an aptitude for them and are only good at one thing but are a prodigy at this, or the way the information is taught and / or then asked in tests does not suit them

13. Could be free going types whom don’t wish to make plans or have commitments and are happy wherever the wind takes them

14. They could fail by being injured in a way that is detrimental to their school advancements
