Scope of practice as a c.a. if completed ca at age 33

Hello,

I have one question for career as a C.A. at age 33.

I am currently doing a job as an accountant. I was doing my CA course and reached till FINAL. For some reasons, I quit the course few years back. Now I am 31 and want to enhance my career by completing CA which I think be completed till I reach 33 years of age. 

I am very much passionate to practice as a CA at this age.

1) My question is, Is there any scope for practice at late age ? What should be ideally done ? 

2) Should I be studying while in job, as I get ample time to study ? or, I should just quit and study ? 

Please, advice on this matter with adequate reasoning so that I can decide on it.

Your replies are always welcome.

Regards,
