What kind of charges am I looking at after being caught with possesion of extacy and sold to an undercover?

I was holding I believe were 9 ecstasy pills and 4 Molly at a rave. They were not mine but my friends for their personal use. My friend got approached by an under cover and told me to give a red ecstasy pill to the girl who tapped my shoulder, to tell her it was 25 dollars. Stupid me when the chick approached me and asked me if I had any "Molly" told her no but I had the red pill my friend mention. Gave it to her and told her it was 25. I was hugging my girlfriend when I got arrested and the group of friend I was with were under the influence of the pills that were theirs. The security took my wallet took all my money and the pills that were left. I have court on the December 26, 2013 and got charged for possession and sell of narcotics. I'm scared for the consequences specially because they were not my pills and I was not asking people to buy she just approached me. I was released from jail the next day and was told to complete some drug classes and present it to the judge on my court day that I attended. I'm 19 years old college student with no criminal record. Am I looking at jail time or what consequences ? Could this be removed from my record ? What can I do?
