  1. can one be admitted to mechatronics for jab with cluster point of 42.3 calculated using the new formula?

    • Hy Nelson.
      Thanks for your interest in our course.
      Please visit jab.uonbi.ac.ke for information on the cut off points. I however have cut off points for last year’s intake which were 47.4 for jab.

  2. I applied for this year September intake. but i found it already full. i submitted as a late applicant .will i still make it?
