I thought this was a good article for AH. It names 7 algorithms that professional programmers should be familiar with but doesn’t go into a lot of detail. That leaves a lot of scope for you to investigate these techniques.

Mini Projects
If you are looking to give yourself a bit of a challenge then try these mini projects.
There is no set level for these and in fact your solution might change as you learn new constructs and data structures.
AH – Cheat sheets for a range of applications
I found these cheat sheets on this site and here. A cheat sheet is a condensed (normally 2 A4 sides) set of notes for an aplication or programming language. They are not designed to be notes in themselves, they are more an aide-mémoire to help you recall how to do something.
There are a lot of languages here but I thought it was worth keeping the list intact. There is a lot in here that is in the course so make sure that you read the entire list.

AH – Scholar Homework Session
The next Advanced Higher Computing Science homework session from Scholar will be on Wednesday 28th September. The topic is “The Object Oriented Programming Paradigm”.
The session starts at 6.30pm.
Logical Operators
Task 18 proved to be a very interesting design challenge. We ended up with a design that required lots of IF..ELSE statements.
AH – Objects and Classes
https://www.youtube.com/watch?v=CtzVNCmysFs
Object-oriented programming (OOP) was discussed in Higher but we didn’t spend a lot of time on it. It is the first “difficult” topic to get your head round in AH. The video above gives a quick introduction to OOP in Python. Python is a OOP language, a topic we don’t dwell on before advanced higher but it was one of the reasons we picked Python for use in the school.
The Scholar notes use Standard Reference Language in their examples, it would be very good practice if you were to code them in Python.
If you are still having problems with Methods, Classes and Objects then you might want a look at the next couple of lessons from Learn Python the Hard Way.
SCHOLAR Higher Homework session
The first Higher Homework session hosted by SCHOLAR will be on Wednesday 7th September at 6.30 pm. This session is on Procedures, Functions and Parameters.
Higher – Past Papers and Review
We have now added 2016 past papers and review to the higher pages. You will also find the new Scholar notes in the higher pages.
N45 – Scratch
Today we covered
- Sequence
- The order that the command are executed in the program
- Stage
- The part of scratch where all sprites are displayed (Screen)
- Sprite
- This is an object in scratch which contains instructions (Script)
- Script
- An ordered list of command blocks which controls the actions of the sprite.
The class used Scratch to create a program animating a knock knock joke, please look inside the program for further help. The class made use of the Cornell Notes system to record the lesson. For homework the class have to write down the sequence of instructions used (program)
AH – LAMP Server Configuration
So the mini notebooks only have windows XP on them, this OS is no longer supported by Microsoft so the first order of business for you is to install a new secure OS. I chose to install Linux Mint on my machine.
The project will more than likely require a web and database server and server side scripting language. I chose to configure the laptop as a LAMP server, a quick web search brought up this site.
You can update your HTML, CSS, MySQL, and PHP skills using codecademy or W3Schools.
