Some ministries like MFA, MINDEF and MHA prefer to recruit the first class honours grads from degrees which we think are 'dead-end', like history, philosophy, or political science. I've heard of seniors (NUS FASS) in these ministries, doing policy work or intelligence.

My personal advice is that if you want to pursue a humanities course, you need to have both the passion and skills to excel, so you will have a greater variety of career opportunities (and higher pay). That said, I've friends who graduated with pass degrees or second lower class who are satisfied with their careers, though they might be doing something entirely unrelated.
