Hello Balmukand Thakur

I hope you are doing good . I would like to know you that you can defintately for ca foundation  . Their is no age limit in ca field , its doesnt matter how many years of gap you have in 12th . It should be passed in any discipline just from a recognised board . I would suggest you just to make the gap certifcate as backup and go for your journey.

Hope you found this answer helpful. Good luck for your future
