Yes, the GMAT Focus employs an adaptive exam format, similar to the current GMAT. Following your response to each question, the exam selects the subsequent question based on your performance up to that point. This method, recognized as the most sophisticated type of adaptive algorithm, enables the test to precisely gauge the score of each test taker. However, it often introduces heightened tension for test takers, as answers must be given in real-time without the option to revise them later.

Yet GMAC is introducing an innovative approach. With GMAT Focus, you have the ability to modify up to three answers in each section, despite the exam’s continued use of question-adaptive principles. This innovation appears to be primarily aimed at alleviating stress during the testing process—an initiative I commend GMAC for taking.

Initially, I had concerns that the limitation of altering only three answers per section could amplify stress. However, the stress of knowing you can modify all your answers is equally challenging. Consequently, this constraint encourages the cultivation of our business-oriented decision-making skills. More often than not, our initial well-reasoned choice is the optimal one, and sticking with it is advisable. Occasionally, circumstances change due to errors or newfound information, prompting an adjustment.

Yet, if uncertainty arises due to self-doubt, it’s best to leave the answer untouched. Your initial response is usually the superior one unless an actual mistake is evident. Moreover, if you find yourself caught between two options, a resolution won’t likely materialize within the next 30 seconds. It’s advisable to cease expending time needlessly, retain your answer, and proceed.
