• Part-D (2 questions) will be descriptive and each question will contain 10 marks

• There is no negative mark or inclusive mark for unattempted questions

• The exam will be conducted offline, so marking two answers of a question is considered as the wrong answer

• Negative marking not only prevents to gain mark but also shorten score by penalty

• The candidates are suggested to mark the answers with accuracy to lessen the impact of negative marking

• The four wrong answers mark deduction value is equal to the one right answer mark gaining value

• To excel in the exam, candidates should focus on accuracy in solving the questions

• The implementation of knowledge works more than the only having information that answers the query "How negative marking affect the score that drives the candidates score below the cutoff?"

• The ISRO implements the marking scheme in the exam

• The candidates have to clear the cutoff to be eligible for the next tier. They have to clear the overall cutoff to come on the merit list

• We should never mark guess based answer

• Reduce time consumption to answer the questions during the exam

9. Preparation Tips and Tricks

• You need to finish three sections of ISRO within 90 minutes, which means you need speed with accuracy in order to attempt 80 questions in total. The more you practice, the better chances you have of acing this exam.

• Remember negative marking is a factor here. Therefore, try not to attempt questions that put you in doubt. 

• Manage your time properly; giveappropriate amount of time to each section. Try to improve your time by practicing as many online tests as possible. Youth4work provides online mock tests will time limit attached to each question; this way one can learn to finish the entire exam within the time limit.

• Studying in a stretch for hours can be tedious and hard and also not so good. Therefore, try to study at several times in regular sessions during a day. This will make learning easy and fun, also you will have enough time to brush up the already studied topics in between intervals.

• It is very important to maintain proper health, so you don’t fall sick on the big day. Give your brain appropriate time to refresh itself. Don’t rush too much information into your head than its limit allows. Take it slow and steady. And get at least eight hours of sleep each night.
