About this course

Learn National 5 and Higher Computing Science online

National 5 and Higher Computing Science cover four areas: software design and development, computer systems, database design and development, and web design and development. Students are assessed by a question paper and an assignment completed in class.

Students often lose marks on reading and writing code in the exam, on SQL queries, and on explaining their testing and evaluation. Higher adds more advanced programming such as file handling, arrays of records and standard algorithms.

Practise Python with our free lessons, or work with an affordable 1:1 mentor who knows the SQA course. Message us on WhatsApp or email, or fill in the short form, for a free, no-obligation chat.

FAQs

National 5 and Higher Computing Science: frequently asked questions

Do you help with the SQA assignment?
Mentors teach the skills the assignment uses and help students practise on similar tasks. The assignment itself must be the student's own work, so mentors never complete it.
Which programming language is used?
Schools can choose the language. Many use Python, which our free lessons teach. Mentors can also work in the language your school uses.
Can you help with both National 5 and Higher?
Yes. We start from the level your student is taking and the topics they find hardest, then plan sessions and practice up to the exam.
Is there a free first session?
The first chat is free and has no obligation. We listen to the student's goals and suggest a plan that fits your budget and timings.
When should we start revision?
Ideally a term before the prelims. A short weekly session plus practice on code reading and SQL builds confidence well before the final exam.
