If there was an interruption during your secondary school or collegiate experience or between your secondary school and collegiate experience (gap year(s)) when you were not enrolled and as a result, not making normal academic progress, explain the reason for the interruption.

The gap year between secondary school and college was mainly due to more time required to prepare for admission in specialised subjects. Preparing for secondary school exams was already a big and time consuming task which left not enough time to prepare for college admission. Hence, it was decided to take a year's gap, prepare full time for the subject of your choice. This really paid off in the end
