A-Level Maths - Decision
Some say it's not even Maths. Some say it's the only real Maths module. Chances are, you're only doing these modules if you're doing Further Maths - and if you're doing it otherwise... each to their own, I guess.
[D1] Definitions
This covers all of the definitions (for graphs) you'll need for your Decision 1 exam in great depth. It's important that you know all of this by heart.
[D1] Minimum Spanning Trees (MSTs)
Kruskal's and Prim's are the name of the game in this topic. Make sure you can tell them apart.
[D1] Complexities
This topic is often overlooked due to its rarity in exams. It's short, you may as well take a look.
[D1] Critical Path Analysis (CPA)
This is probably the heftiest topic in Decision 1, so I've split it into smaller sections to make revising it easier. Personally, I also think it can be the most challenging.
Basics |
Precedency Networks |
Floats |
|
|
Scheduling |
|
Schedule Formation |
Scheduling Charts |
[D1] Linear Programming (LP)
These are the high mark questions which take time. If you're wanting to score high, revise this topic.
Problem Formulation |
Solving Problem |
[D1] Simulation
Fairly simple stuff here, just make sure you follow all the rules.
Assigning Random Numbers |
Queuing Simulation |
[D1] Algorithms
You only need to know a few of these. The rest are just following the steps on your exam paper and being able to tell what they do.
