If you can afford pay Arena Multimedia's fee, which is 35K per semester, I will recommend going there, Their certification is valuable when getting Graphic Designer Job in IT Company. 2nd option is to find someone who is teaching at Arena Multimedia and get Home Tuition, in this way you won't get certificate but you will learn Graphic designing in budget price, Going to any other institute is last and least option, Consider yourself lucky if you get an expert teacher to teach you..
