honestly, for a SPM holder to get 3k per month is consider good,
many cases shows that even degree holder only manage half of your salary,
anyway that not the point, i suggest u go for part-time degree courses or go for professional certificate such as CCNA/MSCE/Linux

i remember my late father told me during his time passed SPM grade 2 already consider very good, can apply for teacher post, but time has changed, nowadays degree holder are everywhere
