Features of SAASTA National Science Olympiad Exam
The South African Agency for Science and Technology Advancement (SAASTA) National Science Olympiad is an annual science competition for high school students in South Africa. Some of the features of the exam are:
The exam covers four subjects, namely Physical Sciences, Life Sciences, Mathematics, and Natural Sciences.
The exam is offered at two levels: Grade 10 and Grade 11.
The exam consists of multiple-choice questions and is usually written in March each year.
Students are given two hours to complete the exam.
Hey I love your story and I will actually appreciate it so much if you can help me with physics…. I’m in grade 10 and I’m just 14 years old….And this is my email address.
I am currently in grade 10 and my first semester results of Physics were abysmal, however, I have gained motivation and I am working on my discipline to pass this subject. I am excited for this, I definitely will not stop entering this competition until I receive a price of my very own. Practicing, practicing, practicing!
