That is, in the conduct of 2020 JAMB examination, it was observed that some CBT centres had varied standards of configuration of network installation.
And this was unfortunately affected the smooth deployment and administration of the examination.
There were cases of candidates and officials that either deliberately orunconsciously disrupted the network by stepping, cutting and/or damaging exposed cables in the examination halls, in fact.
The current configuration in some centres does not allow for quick trouble shooting, and thereby led to unnecessary delay in fixing network challenges.
Technical Advisors and Technical Staff would be visiting each centre in an advance to the commencement of the examination to confirm compliance with these advisories.
Meanwhile, the categorization would be made among the centres whose their network is satisfactory or non.
