There is no worse feeling during a timed section than when you come across a difficult question, have trouble processing it, and feel like you should be able to answer it. You start to question why you can't do it, why your brain isn't working, thinking about the clock, and how you NEED to get this one correct and NEED to do so quickly. This stress can quickly compound and sometimes even render you staring blankly at the page wondering if you can ever do well on the LSAT.
This has happened to me many times during practice and unfortunately many times during real takes; it is not fun. So why does this happen? I think that we tend to take how we feel at the present point in time and assume that we will feel that way for the indefinite future. For example, when we come across a really tough question that we are not understanding, we tend to think that that feeling of difficulty and inadequacy will remain for the rest of the section, rest of our test, and ultimately the rest of our lives. This becomes a very scary prospect. When this is on our mind, it becomes nearly impossible to think objectively or rationally. The idea of hell is so scary because it involves the infinite feeling of suffering.
So, how do you prevent and effectively manage stress before it snowballs? First, know that it is going to be present. No matter how good you are at this test, there will always be very tough questions and ones which do not even come close to clicking at first. Stress and adversity are inevitable. I have found that the key is recognizing stress when it begins. Try to realize when your mind begins to feel uncomfortable and like a question has rendered you weak and powerless. Remind yourself that you have come across some adversity and that this is completely expected and normal. The difficulty that you are having now with this one question is not permanent and you can/will pop right back up for the next one. Move on to the next question with confidence and be ready to skip that one too if it does not click!
This takes practice, but try to recognize the stress/fear/doubt as soon as it arises, tell yourself you were expecting it, and that it will not shake you. When I am hit with stress during a timed section, I like to think "ahhhh there you are! I knew you were coming, but you will not trick me this time." During a timed section you will inevitably think that you can't or that your mojo isn't there, but I promise it usually is! In short, don't project how you feel in the present about a question onto the rest of the test!
Do you find yourself using your LSAT skills a lot? If so, which ones? Congrats on finishing your first semester :)
