The website where Leaving Cert students can see what marks they were given by their teachers crashed earlier due to the volume of people logging in.
The student portal opened at 9 o'clock this morning with many students greeted with an error message.
Students can see what marks they were given by their teacher on the portal and if they were then marked up or down under the standardisation process.
Those who are unhappy with the marks they receive in one or more subjects will have the opportunity to make an appeal.
