Personalised tutoring for GSCE/ A Level Biology and Chemistry
If you are taking GCSE / A Level sciences and want to maximize your chances of getting high grades, this is the class for you. I'm a second-year medical student and remember how stressful and challenging A-Levels can be.
We can go through content on chapters you're not sure about, where I will give you explanations to help build your understanding.
I can set you practice questions and talk through the answers. I will teach you how to score maximum points based on the exam board mark scheme, which will build your confidence when it comes to exam time!
I'm here to help you succeed - if you are interested let me know :)

IB Biology SL tutoring for those in need of extra support with anything biology-related, whether it's to do with anatomy or plants!I completed Biology HL in IB with a 6 overall. I am now studying it at the university level and am ready to help students struggling with IB Biology SL. I am familiar with the syllabus and can help students break down complex topics into simpler concepts that are easy to digest.
We will begin with a lesson in order to get to know each other and see whether our goals align. We will discuss what exactly you need help with and make a weekly tutoring schedule. At the end of every class I expect students to let me know what they need help with next time or tell me 3 days before the next lesson at the latest. This ensures each class makes the most of our time together. At the beginning of the next lesson we will do a few practice questions to revise out previous class and continue with the next desired topic.
I am looking for students who are open to receiving constructive criticism. I promise I will approach all of our lessons with patience, kindness, motivation and support!

Private Lesson Chemistry for Grade 10 - 12, Experienced over 6 yearsChemistry and Physics are fun subjects. Here I want to teach my student how to understand these subjects and solve all the case related to both subjects. As we know, chemistry and physics are close to our life, in every single part of life these subjects are exist. Chemistry exist in our food, body, and every chemical things in our home. Physics is how to we understand all activities we do, such as run, walk, pull or push something, drive car, and so on.
That's why these subject are interesting. We learn these subjects mean we learn all things in our life.
In this class we will try understand the meaning, the reason, the formula and prepare to complete the assignment.
