Hello Ruchi,

1. We recommend that you follow the order of modules sequentially as provided in the material. This will help you understand the concepts right from basics to more advanced well.

2. No, you cannot attempt a test partially and complete the test later, the Test only has one attempt, closing the Test midway will count as an attempt and you will not be allowed to attempt the quiz again.

Only Practice Exercises/Quizzes can be attempted multiple times.
