My Experience
I do have some good advice for CA1 based on what I experienced.
I did CA1 a while ago, and had a very good stab at it. I used the revision books constantly, and found that I could answer all of the questions, and pretty quickly, too.
However, when I actually got to the exam, I found the questions confusing, and there were some questions that I felt were "random."
I seriously wondered what the hell was going on, because I knew that I had prepared very well for it, and was shocked that I was so lost in the exam.
I eventually got an FA for it, and I was pretty unhappy about it too.
When I studied for the retake, I did something slightly different. I realised that the reason why I got lost in the exam wasn't because I was under-prepared - it was because the examiners communicated questions pretty poorly. Therefore, at first glance, the questions could apply to ANY part of the course, thereby making answering the questions real difficult.
Unfortunately for me, I didn't spot this while studying the first time round, because the questions that I did were organised so neatly in groups in the revision books - this meant that I knew what the question would be about before I even did it, hence I knew what type of answer would be applicable (eg a SOUNDER TRACTORS answer).
However, when looking at a whole exam paper, the questions were so vague and poorly worded that I really didn't know where to start.
This leads to what I consider to be my best advice - try to recognise HOW the examiners are asking about certain topics.
Although the questions were vague, I discovered that they had at least been consistently poorly worded and vague for each particular topic.
What I mean is, despite the fact that all the questions looked like they could be asking about just about anything from the whole course, it was possible to spot HOW to distinguish from one type of question to another by recognising that they phrase their questions about a particular topic in a certain way.
It's too long ago for me to remember specific examples, but by way of illustration, a made-up example would be:
Describe how TV affects children's behaviours.
Now, initially, you could write anything under the sun for that question. However, by looking through past papers, you might find, for example, that whenever the examiners asked about behaviours, they were looking for you to write about reality TV programmes.
That's what I mean.
There's still no excuse for poor wording of questions, but at least they've been consistently poor, and if you've done enough work, you'd be able to spot HOW the CA1 examiners ask about certain topics.
BTW, when I found the formula, I passed it the next sitting.
