I would personally suggest you to join Aakash Chennai or Aspirant Academy and take Full Test series and DLP of Allen or Resonance for preparation, or perhaps you could take the Online Class Plan of Allen Kota with all their Top Educators and best faculty inducted in that program.

As far as Allen Chennai is concerned, Anna Nagar is still the leading branch with healthy competiton in all its batches. The faculty here are good but somewhere lack the experience of their own counterparts in Rajasthan as well as than the faculty of Aakash and Other Top Medical Coaching Institutes.
