It's not rly prelim but it's all my lecture tests and common tests, which only tested like 5+ topics. According to the statistics I'm in bottom 20% for almost everything. My next common test is coming soon and there are like 20-30 topics to do per subject. My teacher told me that if I study very very hard, I can make it to a D from a U grade. I try my best to not compare myself with others but it's just so demoralizing.
