Let me tell you the worst that can happen.
If you are still in the school that deboardernised you, you might or will get a bad testimonial after school. The good news is that; several years ago, testimonials were used in acquiring a job or evn scholarships but in GHANA 2014, our gh, testimonials don not mean anything. 90% of SHS from 2006 period up till now do have either not collected their testimonials from the school or have misplaced them. When you are applying for a scholarship, they ask for transcript which contains your academic records in the school so it will not affect you in scholarships application or anything. What it will do is that it wil make you the gossip of your schools empty barrels and also it will make you popular. When your headmistress or headmaster and staff dies sometime in the future, everyone will forget about it and when you graduate from the school, that incident will not step out of your school's gate with you.
IN SHORT, YOU ARE AS FREE TO PURSUE YOUR DREAMS AND ASPIRATIONS ANYWAY YOU SEE FIT. The deboardenisation has very infinitesimal effect on your wonderful life.
