Welcome to Computer Science 20S with Mr. Wachs (see course syllabus). This is the main starting page for this Computer Science 20S course (grade 9 / 10 introductory level), it is the launching point for all content for this course. The main sections of the course are linked to below:

SCHEDULE :
A potential week by week plan for the course that you could follow if taking this course independently (in-school students will follow the class schedule Mr. Wachs sets in the classroom)
CONTENT :
All the unit content for the course including web pages, presentations, and/or videos of the content to learn the theory behind the concepts
EXAMPLES :
All unit examples to accompany the content, to learn the concepts by trying the code examples
ASSIGNMENTS :
All course unit assessments to complete, along with links to the Hand in page and the Hand Back page
HELP :
Resources, links, code, and advice to get help in the course (along with this resources page)

Getting Started:

This main page for this course branches out to other pages and other content (e.g. PDFs, YouTube videos, etc.) to deliver and assess the entire course. If you are physically present in Mr. Wachs’ class at the school, he will direct this content for you. If you are working on this course using the website to get ahead, or working remotely, you have two different ways you can complete this course online:

Follow a weekly schedule: use the schedule page to follow the weeks which will link you to the content, examples, and assessments for each week to keep you on track
Complete the course on your own schedule: work through all course materials for the content, examples, and assessments at your own pace moving from section to section (but be mindful that you need to set a pace that completes the course on time)

Either way, you can get course help and can read this advice from my resources page on how to work on distance education from a web page. If an image is too small to see or read, try “right-clicking” on the image and select “Open image in new tab” to see a larger version of the image.

Remember: you can get always get lots of help on this page, speak with, or email Mr. Wachs at any time!

In addition, you can read this presentation or watch this video on getting started
