How to switch promotion for the same card
 

Hey guys, I am a college student and I've just been approved for a BoA cash rewards card with an $800 limit. I had no credit history prior to this card and no income. Just want to ask, when I applied for this card I clicked on a link which gave $50 cashback for $100 spending. There is actually another offer for the same card which gives $100 for $500. Is there a way I change this to get the 2nd offer instead?

Also, given my success with the BoA card, should I try for any other cards i.e. airline cards? What should my next few moves be? Would appreciate all the help!

Credit card questions should be posted on the Credit Card Programs forum. I'll move it there now.
