You DO need a skills test unfortunately. Must be an LPC, ie the signing of the license by the TRE basically constitutes the passing of the skills test. However you should be able to get a friendly TRE to sign your license even for an OPC if you cover the minimal differences from the LPC. However as you are only missing out by 10 hours on your last LPC may i suggest a few minimal hours that you maybe failed to log previously!
