Dear student

I am a young, motivated, and enthusiastic mathematics, computer science, and study methods teacher.

Students may not always be able to follow along well in certain lessons because sometimes things go fast, and sometimes just need a little more time to understand certain things. Understanding the subject matter is very important. I therefore offer tailor-made extra lessons for every student! Every student is different and learns differently. Because of the teacher training that I have followed and the years of experience in giving tutoring, I know a lot of (online) tools with which students can store things efficiently and better in memory. The student will realize that learning in this way is also much more fun!

Courses in which I give extra lessons:
- Math
- Computer science (Excel, Word, Access, Programming ...)
- Study methods

Feel free to contact me if you have any questions. :)

Below you see several questions to which I can give you a clear and straightforward answer. I can explain this to you at any level and we can go deep where you want it. Is your question not listed? Let me know. There are simply too many questions to write here.

How does the internet work?
How does a computer network work?
What is a DHCP server and how does DNS work?

How do I keep my identity hidden online?
What are cookies?
What does my computer store?
How does the Wehkamp site know that I like those pants?

How does Excel work? and Word? and Powerpoint?
What is a router?
How does WiFi work and can my neighbor on my network?

What is blockchain?

I teach at different levels, if you are interested you can always send an email without obligation with your question. We can then make a personal study plan.
My specialization is internet security, but I got there by gaining knowledge within all facets of information technology. From system administration, network management and explaining the various functions in Windows or IOS to repairing the hardware of a PC.
I studied business informatics at the Hogeschool van Amsterdam. Nowadays I live on Curacao, but I can give great lessons via webcam. And through the possible use of team viewer or G + I can show on your computer how to configure a router, for example. Nothing is impossible ;-)

Experienced and patient teacher of logic for computer science.

I have taught logic, formal languages and automata theory to undergraduates for six years. My tutoring is adapted to the student's level and goals. Whether you need to learn logic for your studies, or you would simply like to know more about the subject, I will be more than happy to help you improve your understanding and skills.

Logic
The sciences presuppose a certain standard of rationality. An ability to distinguish between correct reasoning and claims that do not follow from the assumptions. In this class we study the basic principles of logic and apply mathematical techniques to the study thereof.
Topics include:
Propositional and Predicate Logic
Syntax and semantics
Semantic Tableaux
Natural deduction
Correctness and soundness
Completeness

Formal languages and automata
A formal language is an abstraction of general characteristics of programming languages. Such a languages consists of a set of symbols together with some rules to determine whether a string made up out of those symbols is a member of the language.

Topics include:
Regular languages, context-free languages
Finite automata, pushdown automata, Turing machines
Regular expressions
Regular grammar, context-sensitive grammar
Pumping lemmas for regular and context-free languages

Why me ?
3rd year Bio-engineering Bachelor.
In the past, I taught my now 93-year-old grandmother how to use WhatsApp (which allowed her to make video calls to us during the lockdown period) and how to use other applications on her tablet. I taught my mother, born in the 1960s, how to use the basic functions of her PC. I also gave lessons to 2 other grandmothers in my neighborhood, particularly on how to use the STIB app. Very attentive to personalization, I simplify the material according to each need. I share tips, I provide motivation and organizational techniques on PC or smartphone. Passionate about sharing knowledge, I dissect digital tools to make them understandable.

For complex problems you need mathematics, statistics and computer skills to be able to manage it. Once you can describe a problem in terms of numbers then the solution will follow naturally. Get in touch and I will use real life problems to teach you mathematics, statistics and computer science in a very easy way. These subjects are only difficult if the teacher murders it.
