There are several different places where you can see your account balance.
You can always just go to view your Student Wallet but there are other easy places to see your remaining credits.
1. You can check your balance as shown in the dropdown menu at the top right. Look in your "Student Wallet". Click to view more details like your purchase history.
If you are running low on credits, you can buy more credits.
2. You can see your credit balance on your dashboard, just under your profile photo.
