Grading

10% of your HW2 grade comes from completing the code review in part 3. 90% of your HW2 grade comes from completion of the exercises described in parts 1 and 2.

Part 0: Reading and Checkpoints (SOLO)

This part only concerns reading and checkpoints, and not code tracing or exercises (those are assigned below).

Read all the notes and carefully complete all the checkpoints in Unit 2. While there is no official deadline, you need to complete this step to unlock the HW. We recommend you complete this by Thu 27-Jun at 8pm.

Part 1: Required CS Academy Exercises (SOLO)

This part is entirely solo. It is not collaborative. See the syllabus for details.

For guided exercises, watching the guided video is required -- it will show you how to solve the exercise elegantly, will save you lots of time, and will best prepare you for later exercises. Thus, first read the writeup and then carefully watch the guided video. Then and only then should you solve the guided exercise.

Complete (with green checks) every exercise in the following section:

Part 2: CS Academy Exercises (COLLABORATIVE)

This part is collaborative, as explained in the syllabus. Collaboration is not required but is encouraged. Be sure to properly cite your collaborators!

In this section you will be able to choose between exercises of varying difficulty levels. Choose the ones that are the best fit for you! In each section, there is a required total number of stars you must achieve. Note that 4 point exercises are meant to be quite challenging, so only attempt them once you are confident with the material.

Complete (with green checks) the required number of stars in the following sections: Note: While earning more than the required number of stars is good practice, it will not earn you bonus points except as described below.

Bonus:
If you complete the Integer Data Structures problem, you will recieve 10/8 stars in the Homework 2 Part 2 Section (2 bonus stars!). This problem is for students who want an extra challenge, and should only be completed if you are very confident with the other material. 2 stars are not a lot compared to the time it will take to do this problem, so do it if you're interested, not for the extra points!

Part 3: Code Review

You will be randomly chosen to do a code review in recitation either Thu 27-Jun or Mon 1-Jul. During the code review, you will discuss your HW1 or HW2 code with a TA. This is an opportunity for you to learn how to improve your code, and your grade is determined by active participation.
