Help migrating routes to rails 3 format - ruby-on-rails-3

Question

I am trying to figure out changing this routes.rb to the new rails 3 syntax but it's proving to be quite difficult... I know most of the sutff is simply removing the map.
but some of these routes I cant figure out what they were supposed to do in rails 2 to begin with... so if someone could help me get this to work without deprecation warnings I'd appreciate it'. Please Help.
MyProject::Application.routes.draw do |map|
map.resources :grading_levels
map.resources :class_timings
map.resources :subjects
map.resources :attendances
map.resources :employee_attendances
map.resources :attendance_reports
map.feed 'courses/manage_course', :controller => 'courses' ,:action=>'manage_course'
map.feed 'courses/manage_batches', :controller => 'courses' ,:action=>'manage_batches'
map.resources :courses, :has_many => :batches
map.resources :batches do |batch|
batch.resources :exam_groups
batch.resources :additional_exam_groups
batch.resources :elective_groups, :as => :electives
end
map.resources :exam_groups do |exam_group|
exam_group.resources :exams, :member => { :save_scores => :post }
end
map.resources :additional_exam_groups do |additional_exam_group|
additional_exam_group.resources :additional_exams , :member => { :save_additional_scores => :post }
end
map.root :controller => 'users', :action => 'login'
map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id/:id2'
map.connect ':controller/:action/:id.:format'
end

resources :grading_levels
resources :class_timings
resources :subjects
resources :attendances
resources :employee_attendances
resources :attendance_reports
match 'courses/manage_course' => 'courses#manage_course', :as => :feed
match 'courses/manage_batches' => 'courses#manage_batches', :as => :feed
resources :courses
resources :batches do
resources :exam_groups
resources :additional_exam_groups
resources :elective_groups
end
resources :exam_groups do
resources :exams do
member do
post :save_scores
end
end
end
resources :additional_exam_groups do
resources :additional_exams do
member do
post :save_additional_scores
end
end
end
match '/' => 'users#login'
match '/:controller(/:action(/:id))'
match ':controller/:action/:id/:id2' => '#index'
