Find a Computing tutor for your next step

Computing can involve understanding computers, writing programs and using digital tools. In England’s Computing curriculum, computer science sits alongside information technology and digital literacy: using technology confidently and responsibly. Choose a tutor around the work you need to do.

Here is a small Python 3 example for a learner working on loops. The aim is to add 2, 4 and 6 to make 12, but this code prints 6:

for number in [2, 4, 6]:
    total = 0
    total = total + number
print(total)

The indented instructions repeat for each number. Each time, total = 0 discards the previous total. The program therefore keeps only the last number, 6.

Move that reset before the loop:

total = 0
for number in [2, 4, 6]:
    total = total + number
print(total)

Now the running total becomes 2, then 6, then 12. print(total) is outside the loop, so it displays the final total once. A better explanation is: “Start at zero once, then add each number to the total already stored.”

That explanation matters more than guessing 12. A useful next task is to change the numbers and predict each running total before running the program. These are illustrative teaching examples using Python’s documented loop behaviour, not exam-board questions.

Suppose you are making an Excel worksheet for an order. Put quantities of 3 and 5 in cells B2 and B3, and a unit price of 2 in F1. Leave F2 empty. In C2, =B2*F1 correctly gives 6. But copying it down to C3 changes the formula to =B3*F2: it now looks at the empty cell instead of the unit price.

Use =B2*$F$1 in C2 instead. When copied down, it becomes =B3*$F$1, giving totals of 6 and 10. The dollar signs keep the price cell fixed; the quantity reference changes with the row. Microsoft explains these relative and absolute references.

In this made-up example, the useful skill is identifying which value should change and which should stay fixed. A learner who can explain that choice can apply the idea to another worksheet, rather than copying a formula without understanding it.

In Scotland, the subject is called Computing Science at National 5, Higher and Advanced Higher. Give the qualification name when enquiring so the tutor can discuss the right course. For National 5, preparation can involve software development, computer systems and the database or web development option being assessed.

In Wales, the Made-for-Wales GCSE introduced for teaching from September 2025 specifies Python and uses on-screen assessments. Include the course version and assessment year in your enquiry. For Northern Ireland or another qualification, send the full course title and awarding body from the school’s information. This also helps when moving between school systems.

Look for experience with your stage and the particular language, application or course you use. In the free introductory meeting, discuss how the tutor would approach one current difficulty and what you would work on first. The meeting is for goals, teaching approach and arrangements.

For a learner who finds a screen full of code hard to follow, discuss a shorter example, clear vocabulary and a partly completed trace: a record of how values change as the code runs. Explain any reading, typing or access needs so the tutor can discuss suitable materials and software.
