Science lessons: from elementary to high school

From 28 C$ /h

I am laureate in Scienze Biologiche e Biotecnologie, Indirizzo Ambiente e Agro-Industria.
For 5 years I continue to be students of different età, in diverse corsi di scienze.
Chemistry, mathematics, biology and others are not secret per me.
With this enthusiasm I will wait for others to stop in a very simple way.
Here we learn in the preparation of those written and oral, and in the study of the various disciplines.

Extra information

To be able to make the most efficient possible, you can send in advance arguments, files, and the teacher's schedule. We will work with you to familiarize you with your material so that we can overcome all the problems you have left!

About Me

Since 5 years I have been teaching languages (Italian, Esanol, English and French) and sciences (chemistry, biology and mathematics).
I use the student's instruments, so as not to burden them with something that would not be useful to them.
I am flexible in terms of date and time, and teaching modality
My students are young, from middle school, to college students.
I like interacting with different ages

I graduated with a perfect 45/45 in the IB Diploma and achieved 7/7 in both Biology HL and Chemistry HL. I also have over 3 years of teaching experience.
In this class, I’ll share the strategies, techniques, and exam approaches that helped me achieve those results.
This class is focused on more than simply reviewing the syllabus. We will focus on how to approach IB science questions, apply your knowledge effectively, maximize marks, and consistently perform at a 6–7 level.

What we will focus on:
- How to approach difficult IB-style questions
- Strategies for moving from a 5 to a 6 or from a 6 to a 7
- How to understand command terms and what questions are really asking
- How to structure answers to maximize marks
- Data analysis, graphs, calculations, and experimental questions
- Common mistakes that cost students marks
- Time management and exam strategy
- Challenging 6–7 level Biology HL and Chemistry HL questions

We will work through challenging IB-style Biology and Chemistry questions step by step, focusing not only on what the correct answer is, but why the markscheme awards marks for it and how to recognize similar questions in an exam.
Whether you are currently working toward a 6, trying to push from a 6 to a 7, or simply want to become significantly stronger in IB Biology HL or Chemistry HL, this class will give you a clear and practical strategy for maximizing your exam performance.

We will work adapting to your level and your preferred modality:

BLOCK 1: ALGEBRA
Matrices, determinants, systems of equations, discussion of systems (Rouché).

BLOCK 2: ANALYSIS
Functions, limits, continuity, derivatives, applications of the derivative, graphing functions and integrals. All explained from scratch.

BLOCK 3: GEOMETRY
Vectors, lines and planes in space, relative positions, distances and angles. For Science.

BLOCK 4: PROBABILITY AND STATISTICS
Probability, Bayes' theorem, Binomial and Normal distributions, inference. Fundamental for Social Sciences.

HOW DO I WORK?
1. Clear and straightforward theory, without beating around the bush.
2. EXAM-TYPE EXERCISES. We will do real PAU (University Access Exam) models from Madrid and the rest of the Autonomous Communities from the last 5 years.
3. Tricks to avoid failing in what penalizes the most: planning, notation and time.
