Since I do not have access to GPT-4 Vision yet and someone else might, I will not reveal the year of the paper I will test GPT-4 vision on. Here is a MD5 hash specifying the year, so as to confirm later:

JEE Advanced is one of the hardest tests at a pre-college level in the world.

The marking scheme is as follows:

+4 ONLY if (all) the correct option(s) is(are) chosen

+3 If all the four options are correct but ONLY three options are chosen

+2 If three or more options are correct but ONLY two options are chosen, both of which are correct

+1 If two or more options are correct but ONLY one option is chosen and it is a correct option

0 If none of the options is chosen (i.e. the question is unanswered)

-2 In all other cases

All the options are [A,B) format where A is included and B is excluded. For example, 10-15 will be chosen if the score is 10 or 11 or 12 or 13 or 14 but not if the score is 15.
