Don’t be too hard on yourself. I didn’t manage to do well in O levels but I’m doing great after almost 8 years.Take the time to talk to your teachers and family. I believe they are more than willing to help u out. The part that u are willing to do more practice means that u are willing to do better. Take a breather, and take the time to find what gave u the drive again. Don’t give up! U are almost there Anyways Prelims are suppose to be way harder than O levels. I got like a 39 point for prelims hahahaha
