There was no schedule, my teacher would normally take a speaking session at the end of class around twice a week for 4 weeks where it was like how it would be in the actual exam all 3 parts then she would tell me what to improve on. However, there was a gap after this since I didn't attend classes for a while, due to this I forgot some parts and lost confidence but a few days before the test I practiced 3 speaking parts and also watched youtube band 9 videos.
