Online exam web application at ASP.Net

[MrSaints]

I have ASP.Net online Exam Application. you can see my exam application through below link:http://nicole.nicoleinfosoftdemo.com/ShowTest.aspx?ct=IBPS_BANK_CLERK_HINDI&id=51It is working fine when we run on high speed internet but it gets slow on low speed internet and gets more slow after few questions.I am using ASP.Net on my VPS Server and there very less traffic on my websiteI assume that there is problem due to View State but I am not able to fix it. when I disable the view state, my next question does not come.Please suggest it is problem of View State, Catching or any thing else ?Is it possible to convert whole application into session instead of View State ?I am not ASP.Net Expert so please suggest appropriate solution as soon as possible.Regards,Amit
