If you are thinking about taking it, here is how the exam works.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Four sections of 25 questions<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The exam is divided into four sections, each with 25 multiple-choice questions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Core:<\/strong> general rules, the ozone layer, the Clean Air Act, recovery, recycling and safety.<\/li>\n\n<li><strong>Type I:<\/strong> small appliances, such as household refrigerators and window air conditioners.<\/li>\n\n<li><strong>Type II:<\/strong> high-pressure equipment, such as central and mini-split air conditioners in homes.<\/li>\n\n<li><strong>Type III:<\/strong> low-pressure equipment, such as chillers.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Anyone who passes all four earns the <strong>Universal<\/strong> certification.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What score you need<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Each section is graded separately, and you need at least <strong>70%<\/strong> on each one. If you pass some sections and not others, the ones you passed are kept and you can retake only the ones you are missing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How the exam is taken<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The exam is taken on a computer, online, monitored live by a proctor from an EPA-approved certifying organization. It can be taken in Spanish. The certification does not expire: you earn it once.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to prepare<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Study section by section, starting with Core, which is the foundation for everything else.<\/li>\n\n<li>Practice with mock exams that use the same format as the real exam.<\/li>\n\n<li>Review dates, pressures and recovery requirements, which are the most frequently repeated questions.<\/li>\n\n<li>Do not try to memorize without understanding: once you understand the refrigeration cycle, the questions become logical.<\/li>\n<\/ul>\n\n\n\n<div class=\"ltcf-guia-cta\"><p class=\"ltcf-guia-cta__t\">In our EPA 608 Exam Preparation you study the full syllabus with mock exams and interactive practices, and your
