Should I accept it?

I got an offer by a senior, he asked whether I want to be the vice president for New Tune to replace Juivy because there's a leaking post. Many things couldn't go well without the assist of a vice, our current president likes to take care of things on his own. He's kind but sometimes it won't work this way. He should distribute the job properly and guide those who are doing the work. There's lack of communication between him and another vice prs, that's why they couldn't help each other. And all this while they really need a person to fill up the hole. He said there's no other candidate now, our batch left not much people. The only thing in my mind is that I couldn't handle my studies. There're a lot of presentations, discussions and assignments even though it's just the first month! I feel stress when comes to this. Another is that, I have no experience to be a vice, the highest post I got is only secretary. I can accept this challenge if I want it, but I'm not hoping that I will ruin it. All I want is to donate a little contribution for new tune, to help others up because I am a member of new tune and we are a team. A burden or a responsibility, it's a state of mind. I'm still considering........ Any comment or advice?
