Scholarship

I am rather confused about scholarship indeed. Which scholarship i have to apply, how to apply and what course I should apply. I am not a good decision maker. I need to know that a small decision that i make today will make a big difference in my future. My next plan is to study form 6 if my JPA scholarship application is rejected. May be I will study medics after Form6. My father looks determined to sponsor me if I pursue my study in medical field. My teacher advised my to apply as much scholarship as possible. But the matter is I am 'trap' between medics and engineering. Thus, I need someone to consult me.
