These are questions we have collected from various resources which are being asked in most of the online marine engineering exams, meo class 4 exam, and different companies interview online exams. 

For your ease, we have divided the entire section into Test 1, Test 2, and so on. Each test consists of 50 questions of different types- multiple-choice, fill in the blanks, etc. There is no time limit and no limit on the number of attempts. You can practice as many times as you want. To make it a bit difficult, we have made the questions and options get randomly arranged each time you attempt the test. 

All the best
