 5. Always be prepared for even system design questions! You will never know what comes your way and this is where your projects come in and how much of good practices you apply in them and what do you learn. The [System Design Primer](https://github.com/donnemartin/system-design-primer) is a good start.

 To start preparing for your coding interviews, always begin with a plan. Calculate the amount of time you have left to realistically prepare for your interview from now till the day of the coding test, and carefully make a plan of the topics and questions you will cover per day, prioritizing the most important ones first.
 
-But how do you know which are the most important topics and questions to practice based on the time you have left? You may use the free [Grind 75 tool](https://www.techinterviewhandbook.org/grind75) (built by me) which produces coding interview study plans for varying lengths of preparation time. The algorithm behind it includes a ranking of questions by priority and also a balance between breadth and depth of topics covered.
