Cat prep with job.

So after a lost job offer, year gap, failed gov exams and miserable cat ... Eventually I got a new job and this Monday I joined. No I am planning to restart my cat preperation... So people who did it with 9-6 job please guide me. Even though I am a repeater I think I need to start from scratch. Please share good coaching centres, good resource and what's the time for perfect start. Thankyou in advance.
