Hello aspirant,

To crack a highly competitive exam like gate, a thorough preparation and revision is really important

If you're are really confident about your preparation then go for exam in this year

Or else prepare thoroughly and then give the exam next year

There would be no issue regarding your exam year whether its this year or next year

It is up to  you who should be confidential regarding the exam

Hope this helps you

All the best!

No, there will be no issue. You can give the exam next year also.
