Is Your Child Struggling With Computing?

Many students follow code in class but find it hard to write a working solution from a blank screen under time pressure, or to explain theory such as logic circuits and network addressing precisely in the theory paper. If your child's practical tests or written answers are slipping, a Computing tutor can build up their problem-solving one step at a time and practise both papers with them.

From 2027, when the Singapore-Cambridge Secondary Education Certificate (SEC) replaces the O-Level and N-Level, Computing is examined at G1, G2 and G3. G1 and G2 Computing are new subjects, each with an e-exam and a lab-based paper covering media software, spreadsheets and programming in Scratch.

Common Challenges Computing Students Face

Writing Code From a Blank Screen

Turning a problem into working Python, with valid inputs, correct outputs and data validation.

Testing and Debugging

Trace tables, logic errors and test cases for normal, error and boundary data.

Precise Theory Answers

Binary and hexadecimal, two's complement, logic gates and truth tables, where vague wording loses the point.

Spreadsheet Functions

Picking the right lookup, logical or statistical function, and getting relative and absolute references right.

Networks and Security

MAC and IP addresses, error checks, encryption, and threats such as phishing and spyware.

The Jump to H2 Computing

Data structures, object-oriented programming, SQL databases and web applications built with Flask.

How Our Online Computing Tutors Help

Coding Together on a Shared Screen

Problems broken into steps and solved in Python, with the tutor explaining each line as it is written.

Debugging Your Child's Own Code

Errors in their practice work found and fixed together, so the same mistakes stop coming back.

Theory With Worked Examples

Number conversions, logic circuits and network diagrams worked through on a digital whiteboard.

Lab-Based Exam Practice

Timed tasks on a computer, in the format of the SEC or A-Level practical paper.

Algorithms and Data Structures

Sorting, searching, linked lists, stacks, queues and binary trees, implemented and compared for H2.

Lessons for Every Computing Course

Online H2 Computing tuition

One-to-One or Small-Group Computing Lessons

One-to-one lessons let the tutor read and debug your child's own code line by line. A small group of up to 4 students on the same Computing syllabus, or any class size, is also possible; we'll suggest whichever fits your times first.

How Online Computing Lessons Work

Lessons happen live on Zoom with cameras on and usually last 1.5 or 2 hours, in a regular weekly slot. The tutor writes and runs code on a shared screen, draws logic circuits and network diagrams on a digital whiteboard, and your child codes along on their own computer.

Tutors Who Know Singapore's Syllabuses

Tutors need a deep understanding of the SEC and A-Level Computing syllabuses and their practical papers.

The Same Tutor Every Week

A tutor who knows your child's code and where they left off, for continuity.

One-to-One or Small Group

One-to-one coding help, a small group of up to 4 on the same syllabus, or any class size.

Frequently Asked Questions About Online Computing Tuition

Thinking of Computing Tuition?

Is Computing a Difficult Subject?

It asks for two different strengths: precise theory answers and working code written under time pressure. Many students are stronger at one than the other.

Can Tuition Help a Student Who Is New to Coding?

Yes. Tutors start from variables, selection and loops, then build up to the longer problems set in the lab-based paper.

Which Programming Language Does SEC Computing Use?

G3 Computing uses Python, with JupyterLab and a spreadsheet in the lab-based paper. G1 and G2 Computing use Scratch, a block-based language, and G2 adds microcontrollers programmed with MakeCode blocks.

What Does H2 Computing Cover That G3 Does Not?

Data structures such as linked lists and binary trees, object-oriented programming, SQL databases, web applications built with Flask, and machine learning.

When Should My Child Start Computing Tuition?

Many students start in Sec 3 or JC1, while their programming habits are still forming, or when practical tests show gaps. Starting early leaves time for steady coding practice before the national exam.

Getting a Tutor

How Do I Request a Computing Tutor?

Fill in the free request form above with your child's level and preferred class size, and we'll be in touch on WhatsApp.

Who Are Your Computing Tutors?

Part-time and full-time tutors, current and former school teachers, and undergraduates, matched to your child's syllabus.

Can You Match a Tutor for G1 or G2 Computing?

Yes. Tell us your child's subject level, so we match a tutor who teaches that syllabus.

How Soon Will I Hear Back?

We aim to reply within one working day; after that, your child begins with a trial lesson.

Lessons

How Are Computing Lessons Taught Online?

Live on Zoom with cameras on. The tutor writes and runs code on a shared screen and annotates diagrams on a digital whiteboard.

What Device Does My Child Need?

A laptop or desktop with a camera suits Computing best, so your child can write and run code during lessons.

How Long Are Lessons?

1.5 or 2 hours is usual, at the same time each week.

What If My Child Misses a Lesson?

Message the tutor as early as you can, since you're in direct contact. After a missed group lesson, the tutor can usually share the recording.

Others

How Much Does Computing Tuition Cost?

The fee depends on the level and class size. We confirm it on WhatsApp before the first lesson.

Are There Any Agency Fees?

No.

How Do We Pay, and How Do We Stop?

By PayNow. To stop, we ask for one month's notice so the tutor can plan.

Where Are the Official Computing Syllabuses?
