Frequently Asked Questions
Everything you need to know about CS classes at PhyFix.
Which CS programmes does PhyFix cover?
IB Computer Science (SL & HL), Cambridge IGCSE CS (0478), AP Computer Science A and Principles, Python (all levels), Data Structures & Algorithms, Data Science, and technical interview preparation.
Do I need any prior coding experience?
No — we welcome complete beginners. Our Python for Beginners programme starts from scratch and builds systematically. If you already have some coding experience, your tutor will assess your level and start at the right point.
Can PhyFix help with my IB CS Internal Assessment?
Yes. Our tutors guide IB CS students through the entire HL IA process — from product design and solution planning to coding, testing, and the written report. We help students meet all three IB criteria systematically.
Do you offer Data Science or AI tutoring?
Yes — we offer Data Science fundamentals covering Python, Pandas, NumPy, data visualisation, and introductory Machine Learning using Scikit-Learn. This is suited for students wanting to build portfolios for STEM university applications.
How does online CS tutoring work practically?
Sessions are via Zoom with screen sharing. Your tutor shares code live in VS Code, Jupyter Notebook, or whatever environment you use, and you code alongside them. All sessions are recorded.
