Bhagavad-Gita

Respected Sir ,

         i wanted to ask which commentary on the bhagavad gita should i read or which is in most accordance of the interpretation held by you.
         In my college bhaktivedanta club professor is organising a lecture on introduction to bhagvad gita and there we have been given a copy of bhagavad gita as it is written by hdg ac bhaktivedanta swami srila prabhupada . I may also check the libraray to search a commentry by paramhamsa yoganada.

         Also i wanted to know whether reading books by swami vivekanada , paramhamsa yoganada and bhativedanta swami simulataneously or one after the other may lead to confusion if so then whom should i read first.
