Please Help

I am running a computer education center with my own name. i am exepmted from Service tax as my annual fee colection is less then 10 Lakhs. But for  future, if i divide my student fee in following manner  

1. Tution Fee

2. Computer  lab maintenence charge

3. Building charge

4. Generetor charge -

Will i get exemption on last three point or service tax will be applicable only fro tution fee.

Pl. help me as i am not getting correct answer. My advocate & one exise officer have different view.

thanks
