There are two types of homework which we provide via Panda. These excercises help you to better understand the concepts from the lecture or to realise where you need to have another look into the contents. Especially, it will help you to deal with exercises in the exam. You will also be able to earn bonus points for your grade.
Making a long story short: We strongly encourage you to thoroughly work on the homework.
Type-1 homework deals with the content of one specific week and is designed for repetition and comprehension. It can be solved within a short timeframe, assuming you've already put some work towards understanding the content.
Type-2 homework is designed to deepen your understanding by asking advanced questions (potentially spanning multiple topics). These are more time-intensive and may require you to come up with the right ideas. Solving these excersises grants a bonus for your final grade. Type-2 exercises can be solved in groups. Indeed, teaming up often results in a better understanding and, well, more fun.
