Revised Planning Needed: Be aware of the turn of events and adjust your study schedule and rhythms accordingly.
Tips to Make the Most of This Change
Review and Realign: Adjust your study timetable to the new exam window.
Stick to the Admit Card Schedule: Use the existing admit card—ensure its details match your new allotted shift.
Reach Early: Aim to reach the exam venue at least 30 minutes before each shift begins.
Use the Reading Time: The initial 15-minute window is excellent for strategizing your approach to the paper.
Support for Scribe Users: If using a non-matric level writer, ensure proper authorization to avail extended time.
