I also did the same thing. Will it affect my result?

Yes, your marked answers will be considered for evaluation in NPTEL courses.

When you mark an answer as "review" in an NPTEL quiz or assignment, it means you are temporarily setting it aside for later consideration. Once you have reviewed all the questions and are satisfied with your answers, you can submit the quiz or assignment.

All the answers you have marked will be included in the final evaluation. So, if you have marked an answer as "review" and later changed your mind, make sure to update your answer before submitting.

Remember to submit your quiz or assignment before the deadline to ensure your answers are considered.

Answering a question itself considered as save so you dont need to save it .If you answer a question and also mark it for review, both the answer and the mark will be taken into account during the evaluation process. However, if a question is not answered at all, it will not be considered in the final scoring.

So, in summary, marked-for-review questions that have been answered will be evaluated just like any other answered question in the NPTEL exam.
