questions display in ruby on rails

I have created questions for different module and different exams and
displayed it for creator.... in my view
<%- @questions.each do |q| -%>
<div class="question"><%= q.ques %></div><br>
<span><div class="option-1"><h9>a</h9> . <%= q.ans1 %></div><br>
<div class="option-2"><h9>b</h9> . <%= q.ans2 %></div><br>
<div class="option-3"><h9>c</h9> . <%= q.ans3 %></div><br>
<div class="option-4"><h9>d</h9> . <%= q.ans4 %></div></span><br>
<% end %>
in my controller
def index
@batch = Batch.find(params[:batch_id])
@exam_group = ExamGroup.find(params[:exam_group_id])
@module = StudentAdditionalField.find(params[:module_id])
@questions = Question.find(:all, :conditions=>['exam_group_id=? &&
student_additional_field_id=?', @exam_group, @module ] )
end
I want to display this in a order of module and also in one per page and
radio button
