no no no. you don't have new credit, your credit is still old and well established because you have an old student loan and an old barclays card on your reports. my credit is brand spanking new. everything fell off of mine both good and bad. so you have a big advantage here.
if you look at my scores and cards and limits, i started 8 months ago, i didn't use any authorized user tricks or anything. you should be able to do at least as good as me, but probably much better than me, due to having older accounts on file. especially the loan.
i would say you're doing pretty good so far, pay attention to paying on time and low utilization that's the key thing to scores. and always ask for cli's, i have one coming up with amex next week it might increase my limit to 12k or 18k with them.
