Attempt both the groups together as you have enough time till may 11.Put your best effort and dont think about rank as that itself will put additional pressure on you.However if u end up getting a rank it is well and good.I have attended classes of MP Vijaykumar and he stresses the importance of rank.It does make a difference at the start of your carrier.He says rank holders are given priority over non rank holders particlularly for ur first job.He also said that your first pay will be higher compared to others. Non rank holders will get only what is rejected by rank holders.These words are said by Mr.MPV .But it doesnt mean that if u dont get a rank u wont be successful in life.The institute has a 100%record in terms of job placement.U cant find a single CA without a job today.All the best
