Hello everyone !

Use 2 fingers to type a document or something else? this keystroke will consume you a lot of time!
The typing course that I propose will allow you to acquire a certain speed of typing without looking at the keyboard, because your fingers will recognize, by default, their places on the keyboard.
Do not waste time, learn to type quickly for your use!

I adapt my learning method according to subject and student. Some prefer to understand the whole theory before starting the exercises, others prefer to practice to better understand the theoretical part.
I strongly encourage the student because the state of mind and morale have a direct influence on school results.
I am an understandable person and I always try to take each one in his own way, to give remarks that facilitate the work, to give the tips and tricks necessary to have a good note.
I do exercises and exams corrected.
I always try to do my best to make the student fast able to handle his homework.

Microsoft Office is now a virtually indispensable software suite for almost everyone, whether during our school years, through PowerPoint presentations, document creation with MS Word, calculations and graph creation in MS Excel, or during our professional lives. In the latter case, we need to get even more out of it in a minimum amount of time.

Some may have noticed that it's possible to automate a series of actions by recording "macros" to save time. But have you ever considered that behind these macros lies computer code generated for you in "Visual Basic for Applications" (VBA)? Understanding this type of code and how it manipulates the "object model" associated with the application being used (for example, the worksheets, rows and columns, cells, and the values they contain, in the case of Microsoft Excel) allows you to go further in terms of automation and flexibility.

The course is adaptable to the student and their level. Depending on demand and the number of sessions, it can cover the fundamentals of programming (variables, types, declarations, manipulations, local and global variables, etc.), illustrated using VBA, as well as best programming practices (error handling, using comments, standardizing variable names, code modularity), culminating in the creation of a project enabling interoperability between different Microsoft Office tools (for example, associating notes taken with OneNote with dates in a perpetual calendar created in Excel). It may even cover concepts such as object-oriented programming (polymorphism, encapsulation) and the differences between compiled and interpreted languages.

The sky's the limit :))
