I am a student on the post 2012 student loan repayment plan. Earning a decent salary I do my best to lower the principal of my student loan.

The last two years have seen me accrue interest at a rate of 7.8%. Having graduated in 2016 I still have ~£36,000 left to pay. 

Interest on a public sector loan for education should not be so high and should have a cap of 3%
