My dear friend, it’s a very good question. Even I can tell you that it’s a very interesting question too.
The key points are mentioned here in this question
- Repeater do
- Preparing for NEET
- Extra means additional
- AIIMS
……..
Before starting to explain the entire matter I would like to say that
“IF ANYONE IS VERY STRONG IN PHYSICS AND CHEMISTRY, HAVING STRONG REASONING POWER, HAVING STRONG CONCEPTS BUILDING SKILLS, UNDERSTANDING ON MATHEMATICAL BASED CONCEPTS AND SOLVING POWER IN PHYSICS AS WELL AS CHEMISTRY NUMERICAL CONNECTING MULTIPLE TOPICS INTO ONE, CAN MEMORISING POWER AS WELL AS INTERESTED ON BIOLOGY …ARE THE BEST SUITABLE FOR AIIMS EXAMS…. WHERE THE CANDIDATE IS A FRESHER OR REPEATER DOES NOT MATTER “
