Course Description

Language Alchemy


Have you been learning a language and want to get better, faster, and more efficient, but you don't know where to start? I offer a complex step by step course on how to learn foreign languages in 10 days, but before we continue, I need you to understand that:

  • You will need to study at least 6 hours a day for 10 days to achieve results similar to those presented in the sample video "Learning a language in 10 days challenge part 2". If you can only afford to study, for example, two hours a day, then you will have to adjust your schedule and expand the day limit accordingly,  2h/day≈30days e.t.c (more on that topic in the Lecture 21: Schedule).

  • You will not be advanced after 10 days. You will stutter, you will do mistakes, you will speak slowly, but you will be able to communicate and talk about many different topics.

  • The results may vary slightly depending on your experience, discipline, and the language that you choose. You might do more mistakes or remember a little less vocabulary at the end, but this will not be significant - you will still be able to communicate.

  • I use the word "challenge" for a good reason. This course gives you great results, but in order for it to work, you have to study actively, and you must be self-disciplined.

  • First, you must watch the entire course, and then you can start the challenge.


Course Description:

There are numerous online courses that are devoted to learning foreign languages, however, I have noticed a recurring problem with many of them. There is not enough justice done to the "technical side" of this process. Pieces of advice such as "don't be afraid to speak" or "watch a lot of movies" are of little utility and they usually leave students doing all the hard work on their own. There are several courses regarding this topic, but they usually concern a much more narrow spectrum and mostly a single specific language.


Hence, the aim of this work is to:

  • Help you develop universal linguistic knowledge, owing to which you will be able to learn any language in less time

  • Present you with a method to learn and remember vocabulary and grammar actively

  • Teach you how to learn languages in 10 days so you can achieve similar results to those presented in the video "German in 10 days challenge"

  • Give you a variety of techniques to implement on your way to the C1 level


Remember!

Understanding how languages work and having a basic academic knowledge of linguistics is the most fundamental thing. It is actually what makes polyglots learn languages so quickly. In this course, I will do my best to pass that knowledge to you in a simple way and practical form.


_______________________________________________________________________________________________________________________

Keep in mind that even though this program is very practical as it explains a lot of details as well as talks about different language families, it will not cover thoroughly every single language in the world. It is supposed to build a base that is sufficient to learn languages in 10 days.

I recommend this course to its target audience, but I want to be nuanced, so let me say that it is like learning from an older student, not a professor/instructor, which comes with pros and cons. Pros: There is some very good information in this course. I will be using many things in this course for my own language learning in the future, and I think the way thing are broken down will help me quite a bit. Out of respect for the fact that this is a paid course I will share no specific examples here. Cons: As a teacher, Garstka is rough. This course feels incredibly unfocused, and I do feel like I had to hunt for the useful knowledge in it. There are also times where he feels uncertain of the specifics, like he is remembering something offhand rather than having taken the time to be sure of it before beginning his lecture. But most of all, he is a rambler. Boy does this many ramble, repeat himself, and go down rabbit trails. This course has 10hrs of video, but due to his lack of focus less than 5 is devoted to meaningful content. As bad as those cons might sound, I still recommend this course to interested parties because it's all about how to learn a language on your own. If you are going to learn a language in 10 days, or simply make a push to conversationality, then you wont have a teacher holding your hand. If you are the kind of person who is willing and able to use Gastka's methods, then you are probably the kind of person who will be able to sift through his unfocused rhetoric

The music was a little distracting but nice. Also, The teacher spent a lot of time speaking in Spanish, French, and German. I realize that the point is to show how much he learned in 10 days, but since I don't understand those languages, I found myself jumping forward.

Çeşitli dilleri ve yapılarını ele aldığı için çok zaman sarf ettiriyor, ve verilen bilgilerin takibini zorlaştırıyor. Benim tavsiyem, diller arasındaki benzerlik ve farklılıkları 60 dakika içince özetleyip sonra bir dili ele alarak (örneğin İspanyolca) 10 gün içinde bu dili öğretecek bir model önermesi. Bu model benzer dil yapılarında kullanılabilir. Farklı dil yapıları için başlangıçta vereceği ipuçları ile nasıl bir yol izlenebileceği hakkında bir takım ipuçları vermesi programın kalitesini arttırır.

This is invaluable information. It teaches you the framework of how to acquire the ability to communicate in a foreign language. I am an English native learning Russian and I was very disappointed with the Russian teachers and courses that I tried. There was a lot of information and vocabulary and grammar, all the tools to make sentences but something is missing. It is like building a house and having all the tools, and blueprints to build a house but you still need someone that has experience building a house to help you build it so that you can build it efficiently and properly. This course almost does that. The only thing missing is the experienced person that has already learned Russian that can help a beginner learn Russian. Because I realized that this theory in this Udemy course is solid, but there needs to be courses produced that take the theory and applies it step by step in each language.

By Bruno Dominoni de Araujo on 4/18/2021

O curso é interessante, mas, ao meu ver ele foca mais nas diferenças de cada língua do que no método em si. Por tal motivo, deliberadamente saltei alguns trechos, pois não tinha o interesse em saber, por exemplo, a fonética do Mandarin. Creio que o foco deveria se dar mais no como fazer (preparação, estudos, forma) do que nos detalhes de cada língua. Creio que faltou materiais em PDF também. Ao menos a tabela com os Pilares 1/2 poderia ser fornecido em PDF. Ainda sim dou 3 estrelas, pois o Instrutor tem o conhecimento de linguística e propõe um método interessante.

By Piotr on 12/27/2020

It's very good. I'd recommend it to anyone who either wants to learn a language in a quick and practical way or aims to become a polyglot and master many languages.

By Damian Buczak on 12/27/2020

Kurs jest bardzo ciekawy. Pokazuje dobre sposoby jak zacząć się uczyć. Chciałbym mieć w sobie jeszcze tyle skrupulatności. Podsumowując kurs na prawdę mi pomógł. Jestem osobą, której ciężko przychodzi nauka. Z tym kursem zrobiłem krok do przodu może nie w 10 dni, ale i tak się cieszę z progresu jaki osiągnąłem.

By Armand Onak on 12/26/2020

The course was super prepared, the accent was clear, everything was understandable. If someone is looking for an online course and wants to learn something, I recommend this course.
