Hello dear aspirant,

Yes you can if you solve unsolved section first and analysis the accuracy rate.

If you found maximum no of attempts are going correct then there is a possibility of getting rank under 1000.

And the better option would be try to give mock test regularly and find out the main mistake what is going wrong and try to rectify it analysis it thoroughly.

Definitely by giving test u can score good if you improved your mistake well.

Thank you

All the very best
