HELLO ASPIRANT,

it actually depends  on the student on how he takes on the exams, he can make the best use of it in every terms , but what matters is that is he using a legal method or an illegal method of doing so,

the fate of this type of exams is decided in this way only,

there can be many advantages and disadvantages too-

ADVANTAGES OF ON DEMAND EXAMINATION

It Allows the student to get assessed when he/ she is ready.

Attempts to remove the stress of appearing in examination(s), whether for all subjects or in one subject at a fixed time and schedule.

Attempts to remove the threat of failure in examination.

Removes frustration, loss of self esteem, peer group ridicule, depression etc.

DISADVANTAGES

(I) Unfair Checking of Exams

(II) During practical's They'll openly ask you to pay money and get marks

(III) Many private universities dont' recognise the exam pattern.

it actuall depends on us as how do we utilise the opportunity.

I hope that I have cleared your doubts

All the best
