Still a dip...
1: go to a private uni locally or oversea
2: go skillsfuture since you already have a diploma
3: take a level as private candidate and hope that you can enter uni
4: go to find a job
5. do what you want and enjoy life
6. self study some stuff and apply it in whatever you will be doing
1,2,3 and 6 are the only options if you want to study further
I did mine in 16 months and did pretty good
