Your RC is drastically worse than your SC and CR - close to random guessing. I would start by reviewing the principles of RC (the beginning of the MGMAT RC
strategy guide is the source I know about, but there are many others too). Then start reviewing all the questions you missed, from easiest to hardest, and remember: STUDY SLOWLY.
Don't move on until you understand everything about that problem. Why is the answer you picked wrong? Why is the right one right? Did you fall for a trap? Did you take bad notes? You need to figure it out before moving on.
Also, I noticed that the avg level right for your SC is equal to avg level wrong. This means that you are not missing because questions are hard, you are missing because you don't understand some of the topics. Remember that most SC problems test more than one issue: you may feel like you are doing well at SC because you always find a problem, but now you need to go back and check whether you are finding ALL the problems. As with RC: STUDY SLOWLY.
Review everything before you try new problems to make sure you learn.
I hope this is enough to get you started. Maybe others here can help out too!
I will keep track of my error logs to get a better understanding!!
