Hi, I’m Sofía. I teach IB English A: Language & Literature (SL/HL). Most of my work is Paper 1 commentary, Paper 2 essay planning, and helping students stop “retelling the plot”. I studied English Philology at the University of Costa Rica and spent three years editing NGO reports, so I’m fussy about argument, register, and citations. Bring a draft or an extract and we’ll work line-by-line. I can also help with HL essay outlines and quotations.

I tutor IB Maths AA (SL/HL) and keep lessons very exam-shaped: short starter, one tough question, then timed practice. I’ve run DP revision workshops where we mark with the IB scheme, so you’ll see exactly why a method earns (or loses) points. Calculus and functions are my favourite, but I also cover statistics properly—interpretation, not just button-pressing. I’ll show you quick checks to catch silly errors before you hand it in.

I’m an IB Biology (SL/HL) tutor with a research background in tropical ecology. I’ve supervised student IAs on enzyme activity, transects, population sampling, and data processing (uncertainty included). I’m good at turning a messy idea into a testable method and a clear write-up. In lessons we use the syllabus statements, then practise writing answers in the tight wording IB markschemes reward. I’m also happy to sanity-check your IA conclusion against your data.

Hi! I teach IB Chemistry (SL/HL). Before tutoring full-time, I worked in a quality-control lab in food processing, so stoichiometry, titrations, and calibration curves are second nature. I’m happy to reteach topics, but I’m most useful for IA planning: choosing variables that actually change, building a results table that makes sense, and writing evaluation without waffle. Past-paper question sets are my go-to.

I’ve been tutoring IB Physics (SL/HL) for years, mostly with students who know the theory but lose marks on setup. We’ll focus on diagrams, assumptions, units, and showing a method the way IB expects. I also support Physics IAs—selecting sensors, controlling variables, and writing uncertainty and limitations properly. If you like, I’ll bring a “common traps” list from real past papers and we’ll drill them.

I tutor IB Economics (SL/HL) and I’m strict about doing it the IB way: clean diagrams, clear chains of reasoning, and evaluation that goes beyond “it depends”. I’ve coached plenty of IAs, from picking a focused article to linking it to the right concepts and writing effective commentary. For Paper 1/2, we practise timing, paragraph structure, and the little definitions that quietly earn marks. I keep a set of “diagram drills” for the big HL topics.

I’m an IB Psychology (SL/HL) tutor with experience assisting in behavioural research. I help students learn studies efficiently—aim, method, results, then evaluation—so you can actually use them in essays. We’ll practise SAQs and ERQs with command terms, not guesswork. For the IA, I can guide design choices, ethics forms, data analysis, and writing it in the exact IB format (tables, appendices, all of it).

If you’re taking IB Computer Science (SL/HL), I can help with both the theory and coding. I’ve taught programming clubs (Java/Python) and I’m patient with debugging—screen share, reproduce the bug, fix it together. We’ll cover algorithms, OOP, and exam-style pseudocode. I’m also strong on the CS IA: scoping a project that’s doable, writing success criteria, and documenting development clearly. If your IA is already started, we can rescue it and tighten the criterion links.

I teach IB Business Management (SL/HL). I worked in operations for a small export company, so the finance bits and strategy tools aren’t just textbook to me. I can help you write answers that feel like real decisions: stakeholders, constraints, and justified recommendations. I’m especially useful for the IA—finding a focused research question, choosing appropriate tools, and keeping analysis/evaluation balanced and IB-friendly.

I tutor IB Geography (SL/HL) and have a background in planning and GIS. If case studies are your headache, we’ll build a small bank you can actually deploy, with stats and place-specific detail. I’m big on command terms and concise evaluation for Papers 2/3, plus sketch maps and diagrams that don’t eat time. I can also guide fieldwork-style IAs from question design to data presentation and conclusion.
