i recently spent tons of time dealing with PTPTN to settle my loan. If you signed after certain date- think 1/6/2008 (pls check site to confirm)- then ur interest is 1%. Otherwise, its 3%.

According to the agent- the only way u can be entitled to 1% if signed before the effective date is if you settle lump sum. And even then- its only calculated from that date and not before.. i.e. if i sign in 2003 and finish studies in 2006 and and from 2006 to 2010 i must pay back by installment- and if i choose to pay lumpsum in 2010- i will pay interest 3% until 31/5/2008 and 1% from 1/6/2008 till full payment in 2010..
