The joy of getting itLearn together

A question is a great start.

That “now I get it” feeling.

More questions. More clarity. More confidence.

Human connection

A real person in your corner.

Room to ask

No question is too small.

Lasting understanding

Go beyond getting the answer.
Services

A little support. A lot of possibility.

Pick the path you're on. Most students know which one they need.

Exam Prep

AP Computer Science A, IGCSE Computer Science, and other major board syllabi — taught to the mark scheme, not around it. We go past "understanding the concept" into "scoring the point": past papers, examiner language, common trap questions, and the exact structure graders look for.

Build Real Things

Python, JavaScript, TypeScript, Java, SQL, and the frontend-to-backend path. For students, career-switchers, and hobbyists who want to actually ship working code — not just finish a course. We build real projects, debug real errors, and learn by doing.

How it works
  1. 1

    Book a trial

    Tell me what you're working toward — an exam, a project, or just "I don't get this yet." We use the first session to figure out where you actually are.

  2. 2

    We build a plan

    A short, honest plan based on your syllabus or goal — not a generic curriculum copy-pasted for everyone.

  3. 3

    Weekly sessions, real progress

    Consistent 1-on-1 time, adjusted as you go. If something's not working, we change it — not stick with it because it's "the plan."

Progress is a practice.

Small steps count.
About Microcohort

Learning is personal.

I'm Zain — I teach Python and computer science on Preply, and I built microcohort.org for students who want more than a generic course. I've worked with students prepping for board exams and students just trying to understand why their loop won't terminate at 1am before a deadline. Both deserve someone who explains it properly the first time.

No script. No filler. If you're stuck, we stay on that one thing until it clicks — then we move on.

Good questions

A little clarity before you begin.

Still wondering about something? Start with a question.

Ask Zain a question

Hourly tutoring is $12 USD per hour with a free trial lesson. Complete CS book preparation is $499 USD as a one-time fee, including quizzes, exercises, mock exams, and revision.

Both — most students pick one track, but a few do both (e.g., an IGCSE CS student who also wants to learn Python outside the syllabus).

That's most students. We start from wherever you actually are, not wherever the syllabus assumes you are.

For exam prep, yes — the board's syllabus and mark scheme. For coding tracks, it's built around what you want to make or learn, adjusted weekly.

1-on-1, online, live — not pre-recorded. Screen-share, live coding, real-time feedback.

Yes — that's exactly what the trial session is for.
