Hello aspirant,

To crack one of the highly competitive exam like gate,a good preparation and revision is important.

Giving Mocks is really a good thing to know your strengths, weakness

I think quality of mocks and analysing them is really important than to increase in number of mocks

It is worth less to give more and more mocks if its is not of a good quality level

So I think if you're comfortable at giving official mocks it's ok but analysis is very important

Hope this helps you

All the best!

You can do that, and you can also buy the online mocks available in the market. Both will be good.
