Hello aspirant,

I hope that you are doing absolutely great.

With reference to your above mentioned query, I would like to tell you that you can apply for both of these Phases in SRMJEE. The Syllabus and exam pattern will be same for both of these phases so, phase 3 will not be much difficult as compared to phase 2.

Further, you should apply for phase 2 and phase 3 as giving exam in both of these phases will make you well prepared with the exam pattern and will help you to get familiar with the type of questions in the examination. After giving phase 2, if it doesn't goes so well, then you can also apply for phase 3 of SRMJEE also. So, you'll always have a backup .

The best of two sessions will be taken in to consideration for merit list which means that the highest score will be taken in to consideration. The applicant can apply for either one or both the sessions depending on their interests.
