I am giving you Idea how to Solve your Problem. See the image i have selected and the i have checked what i have selected.

Create Dictionary To Store your Selected Radio Button as per question

Dictionary dc = new Dictionary();

Bind your RadioButtonList

selected index code Save your value in Dictionary

Session["val"] =Session["val"]+","+ RadioButtonList1.SelectedIndex;

string val = Session["val"].ToString();
val = val.Remove(0,1);//;.Remove(1, 1);
Response.Write(val);

char[] separator = new char[] { ',' };

string[] strSplitArr = val.Split(separator);

foreach (string arrStr in strSplitArr)
{
Response.Write(arrStr + "
");

RadioButtonList1.SelectedIndex = Convert.ToInt32(arrStr);
int index = Convert.ToInt32(RadioButtonList1.SelectedValue);
string valu = RadioButtonList1.SelectedItem.Text;
dc.Add(valu, index);
Session["dic1"] = dc;
}

Add Your selected value in Dictionary

Display Selected Question n Answer

foreach (var pair in (Dictionary)Session["dic1"])
{
Response.Write(pair + "
");
}

in prevoius Button Click

Select Last Record From Dictionary new prevoius minus 1 last index
