Hello my dearest student,
Keep ur best in those 3 hours till last second.
Don't spend more time on one question only.
Complete exam in 2.15 hours only, remaining time try for leftout questions.
Don't regret after exam so plan now to give best shot in those 3 hours.
Go to exam centre before one hour. Don't eat nonsense.
Gate exam is not life, it is one of the best opportunity to show ur ability, so keep ur best.
If you get good rank then one of the good dog will marry you, otherwise good pig will marry you. So finally you will marry, don't worry.
I know very well u will give ur best shot because all of u did hardwork
All the very best
