Hie everybody

I have a Bachelor's degree (3yrs) in Arts. I am thinking of higher studies abroad not sure where (actually no idea). I dont know even from whre to start. I know I have to take either TOEFL or IELTS. Since my undergraduate degree is of 3 yrs only, do this will affect my application or what will happen, or do I have to take extra courses. If somebody explain me clearly, I will appreciate your help. Thank you.
