Phobia.

This may be funny but true. Some students do fear computer system as if it can harm them. This I know from my knowledge as a computer instructor, if you instruct some to even type their names using the keyboard, you will see them fidgeting as if the computer will swallow them.If someone can not use it to type his or her name, and you want same student to run an examination on it.... You don't need to be a seer before you can predict the outcome of the result of such student.

Students' perception to CBT.

Naturally average human being harbors 'change'. This has affected the students psychologically, because they are reluctant to change. The are used to paper and pencil or say pen type of examination.

This will make some of them to fail the examination even before they leave home for the examination. And conceding defeat before the battle will tantamount to real defeat when the battle starts.

Modus operandi of the examination:

The way CBT examination is arranged is far different from the conventional system of pen and paper. With pen and paper, you have access to all the questions at a glance but the reverse is the case for CBT.

In a situation where you have just a question on the screen and the answer is not forthcoming, their will be an unofficial impediment or say delay but there is a chance to skip it but their is a little or no chance to re-visit it after treating like the next 5 questions.

This equally contributes indirectly to the high rate of failure being recorded as well.

Time:

Time they say is the bedrock of all examination. If an examination that suppose to be for 2 hours can be written in 10 hours, I'm sure virtually all the students will pass it.

Most students complain of short time frame for the examination. Some of the questions are time-bound, that is, say 15 seconds for a question.

In this scenario, if a student uses 25 seconds on such question, it will have multiplier effect on the next questions and this may make such student to come out woefully.

Not having exposure to stereotypes

This is a very serious issue, being brilliant does not matter here. Even a professor can have a poor outing in this type of situation.

Some of these students have not seen how the CBT works before, most especially people living in the rural areas that have no or little access to ICT.

Inadequate preparation:

This may not be linked directly with CBT but in a situation where the students fails to plan by preparing well for the examination, the output will be nothing to write home about.

You can only deliver what you have in your brain. Like this saying "proper planning prevents poor performance"; this implies that improper planning will definitely breeds poor performance.

Inadequate preparation:Reduction in examination malpractices:

This I ought not to have added but it is still part of it. Before now, some students rely on helps to pass examination

But with CBT, you are on your own (OYO). The person close to you might not be attempting the question you are battling with presently and everyone is working towards beating the time.

I think CBT was introduced to curb this primarily and for real, it has drastically reduced examination malpractices.
