Thanks for the comprehension. 42 | 43 | > **"How can I do this?"** 44 | 45 | Just create an account on GitHub and log in with this account in our web app. 46 | 47 | The intention of this app is to offer for our students a way to track their progress, and also the ability to show their progress through a public page for friends, family, employers, etc. 48 | 49 | In the "My Progress" tab, you are able to edit the status of the courses that you are taking, and also add the link of your final project for each one. 50 | 51 | ## Motivation & Preparation 52 | 53 | Here are two interesting links that can make **all** the difference in your journey. 54 | 55 | The first one is a motivational video that shows a guy that went through the "MIT Challenge", which consists of learning the entire **4-year** MIT curriculum for Computer Science in **1 year**. 56 | 57 | - [MIT Challenge](https://www.scotthyoung.com/blog/myprojects/mit-challenge-2/) 58 | 59 | The second link is a MOOC that will teach you learning techniques used by experts in art, music, literature, math, science, sports, and many other disciplines. These are **fundamental abilities** to succeed in our journey. 60 | 61 | - [Learning How to Learn](https://www.coursera.org/learn/learning-how-to-learn) 62 | 63 | **Are you ready to get started?** 64 | 65 | ## Curriculum 66 | 67 | -

Participate in Kaggle competition 175 | - List down other ideas 176 | 177 | 178 | ### Specializations 179 | 180 | After finishing the courses above, start your specializations on the topics that you have more interest. 181 | You can view a list of available specializations [here](https://github.com/open-source-society/data-science/blob/master/extras/specializations.md). 182 | 183 | ![keep learning](http://i.imgur.com/REQK0VU.jpg) 184 | 185 | ## How to use this guide 186 | 187 | ### Order of the classes 188 | 189 | This guide was developed to be consumed in a linear approach. What does this mean? That you should complete one course at a time. 190 | 191 | The courses are **already** in the order that you should complete them. Just start in the [Linear Algebra](#linear-algebra) section and after finishing the first course, start the next one. 192 | 193 | **If the course isn't open, do it anyway with the resources from the previous class.** 194 | 195 | ### Should I take all courses? 196 | 197 | **Yes!** The intention is to conclude **all** the courses listed here! 198 | 199 | ### Duration of the project 200 | 201 | It may take longer to complete all of the classes compared to a regular Data Science course, but I can **guarantee** you that your **reward** will be proportional to **your motivation/dedication**! 202 | 203 | You must focus on your **habit**, and **forget** about goals. Try to invest 1 ~ 2 hours **every day** studying this curriculum. If you do this, **inevitably** you'll finish this curriculum. 204 | 205 | > See more about "Commit to a process, not a goal" [here](http://jamesclear.com/goals-systems). 206 | 207 | ### Project Based 208 | 209 | Here in **OSS University**, you do **not** need to take exams, because we are focused on **real projects**! 210 | 211 | In order to show for everyone that you **successfully** finished a course, you should create a **real project**. 212 | 213 | > "What does it mean?" 214 | 215 | After finish a course, you should think about a **real world problem** that you can solve using the acquired knowledge in the course. You don't need to create a big project, but you must create something to **validate** and **consolidate** your knowledge, and also to show to the world that you are capable to create something useful with the concepts that you learned. 216 | 217 | The projects of all students will be listed in [this](https://github.com/open-source-society/data-science/blob/master/PROJECTS.md) file. Submit your project's information in that file after you conclude it. 218 | 219 | **You can create this project alone or with other students!** 220 | 221 | #### Project Suggestions 222 | 223 | 224 | 225 | And you should also... 226 | 227 | ### Be creative! 228 | 229 | This is a **crucial** part of your journey through all those courses. 230 | 231 | You **need** to have in mind that what you are able to **create** with the concepts that you learned will be your certificate **and this is what really matters**! 232 | 233 | In order to show that you **really** learned those things, you need to be **creative**! 234 | 235 | Here are some tips about how you can do that: 236 | 237 | - **Articles**: create blog posts to synthesize/summarize what you learned. 238 | - **GitHub repository**: keep your course's files organized in a GH repository, so in that way other students can use it to study with your annotations. 239 | 240 | ### Cooperative work 241 | 242 | **We love cooperative work**! Use our [channels](#community) to communicate with other fellows to combine and create new projects! 243 | 244 | ### Which programming languages should I use? 245 | 246 | Python and R are heavily used in Data Science community and our courses teach you both, but... 247 | 248 | The **important** thing for each course is to **internalize** the **core concepts** and to be able to use them with whatever tool (programming language) that you wish. 249 | 250 | ### Content Policy 251 | 252 | You must share **only** files that you are **allowed** to! **Do NOT disrespect the code of conduct** that you signed in the beginning of some courses. 253 | 254 | [Be creative](#be-creative) in order to show your progress! :smile: 255 | 256 | ### Stay tuned 257 | 258 | [Watch](https://help.github.com/articles/watching-repositories/) this repository for futures improvements and general information. 259 | 260 | ## Prerequisite 261 | 262 | The **only things** that you need to know are how to use **Git** and **GitHub**. Here are some resources to learn about them: 263 | 264 | **Note**: Just pick one of the courses below to learn the basics. You will learn a lot more once you get started! 265 | 266 | - [Try Git](https://try.github.io/levels/1/challenges/1) 267 | - [Git - the simple guide](http://rogerdudler.github.io/git-guide/) 268 | - [GitHub Training & Guides](https://www.youtube.com/playlist?list=PLg7s6cbtAD15G8lNyoaYDuKZSKyJrgwB-) 269 | - [GitHub Hello World](https://guides.github.com/activities/hello-world/) 270 | - [Git Immersion](http://gitimmersion.com/index.html) 271 | - [How to Use Git and GitHub](https://www.udacity.com/course/how-to-use-git-and-github--ud775) 272 | 273 | ## Change Log 274 | 275 | 276 | 277 | ## How to collaborate 278 | 279 | You can [open an issue](https://help.github.com/articles/creating-an-issue/) and give us your suggestions as to how we can improve this guide, or what we can do to improve the learning experience. 280 | 281 | You can also [fork this project](https://help.github.com/articles/fork-a-repo/) and send a [pull request](https://help.github.com/articles/using-pull-requests/) to fix any mistakes that you have found. 282 | 283 | TODO: 284 | If you want to suggest a new resource, send a pull request adding such resource to the [extras](https://github.com/open-source-society/data-science/tree/master/extras) section. 285 | 286 | The **extras** section is a place where all of us will be able to submit interesting additional articles, books, courses and specializations, keeping our curriculum *as immutable and concise as possible*. 287 | 288 | **Let's do it together! =)** 289 | 290 | ## Code of Conduct 291 | [OSSU's code of conduct](https://github.com/ossu/code-of-conduct). 292 | 293 | ## Community 294 | 295 | Subscribe to our [newsletter](https://tinyletter.com/ossu). 296 | 297 | Use our [forum](https://github.com/ossu/forum) if you need some help. 298 | 299 | You can also interact through [GitHub issues](https://github.com/open-source-society/data-science/issues). 300 | 301 | We also have a chat room!
