How to create a link directory WP Blog

I’m very new to WP so please excuse me. I just need help in a pointing me in a general direction. I’m trying to build a simple small searchable, usable directory of online courses. One a user can browse by category. Some courses will be appear in multiple categories (Science, School Ect) and the pages just need a small description & link. I tried the directory software on here, but I don’t want users to be able to submit pages, or be able to rate or comment on links. What direction should I go in to do this?
