Our test taking platform is similar to the actual exam. Just like in a real test, you can skip questions during taking a test on Embibe so as to avoid negative marking for answering questions which you are not sure of.
However, skipping questions during practice is not allowed. You can make use of the "Hint" option to solve questions that you find difficult. This is because the questions on Embibe are adaptive; we develop your ability to solve the problems by providing you with hints throughout the practice sessions.
