Hello! I'm sorry that your studies have stalled out. :/
We need to dig a bit deeper into the data analysis (and by "we," I really mean "you"
I can't actually tell, for example, where you guessed and got lucky or where you knew what you were doing but made a careless mistake. I need you to tell me.
Use this to help you analyze all of the data:
http://tinyurl.com/analyzeyourcatsSet aside at least an hour (probably longer) and dig in. Then tell me what you've figured out.
Also, look for things that:
(1) You got right but you were on the 2+ min side: is there a more efficient approach? Or can you get better / more efficient at the approach you did use?
(2) You got right but any part of it felt clunky / annoying. What's a better way? Or what do you need to practice so that it feels less clunky?
(3) You got right this time but could see how you might not always get that right. What do you need to do to move the needle more towards "I'm confident I'll always get something like this right."
(4) You got wrong but it was a careless mistake. How to minimize that type of mistake in future? (Don't just tell yourself what you "should" do. Drill it. Make the remedy a habit.)
(5) You got wrong but the explanation makes 100% complete sense and you're like, yeah, I can totally do that next time. Or you used to know it but forgot because you haven't reviewed it in a while. Practice whatever that is.
Notice that I don't have "you got wrong and the explanation didn't make a ton of sense" as a category. That's because the proper strategy for those is "bail." You don't have to study any actual content to be able to do that—you just have to be able to recognize that this problem sucks for you and you don't want to do it.
Let me know what you've got when you're done with your analysis!
