Thousands of pupils across Scotland sit SQA exams
Over 2 million question papers will be handed out over the next week.
Hundreds of thousands of pupils across Scotland are sitting their National 5, Higher and Advanced Higher exams.
More than 2 million question papers will be handed out over the next six weeks in schools, colleges and training providers.
Education Secretary Jenny Gilruth said: "I want to wish everyone the best of luck with the exams.
"I am confident pupils are well prepared for these assessments because their teachers have been putting on study classes for them during the Easter holidays.
"The previous Education Secretary also made sure there were extra resources available for pupils when teachers were on strike."
Almost 130,000 candidates will sit formal assessments, with learners undertaking question papers in subjects ranging from Chemistry and English to Art & Design and Environmental Science.
For those candidates taking subjects such as Drama, Health and Food Technology and PE, the performance and practical elements of the assessments have been taking place over the last several weeks.
Iain and Ruby are in S6 and already have unconditional offers for university.
They told Greatest Hits Radio: "We want to do well this year, but we know we have a place on a course which takes the pressure off.
"It can be a very stressful time for all of us."
Fiona Robertson, SQA Chief Executive, and Scotland’s Chief Examining Officer, said: “I would like to wish the thousands of young people throughout Scotland who are about to sit exams or complete their assessments the very best in the coming weeks.
"This is their opportunity to demonstrate what they have learned and what they can do, to progress to their next steps in education, training, or employment.
“I also express my appreciation for the dedication and professionalism of teachers and lecturers across the country, who have continued to support and guide thousands of learners, helping them reach their full potential.
“We couldn’t do what we do without the support of thousands of appointees, including thousands of practitioners, who collaborate with us throughout the year to ensure the exams and assessments are set, invigilated, marked, and quality assured.
"They bring a wealth of expertise from the classroom and play a crucial role in ensuring that learners' hard work is recognised.”
