Hi Ankita,
AIIMS has not defined any limits for its ug exam syllabus. It has vaguely stated that its syllabus will be that of 10+2.
AIIMS paper (online computer based test) is of 200 marks comprising 200 MCQs, each MCQ when answered correctly gets you 1 mark and when answered wrongly, deducts 1/3 marks. You can also skip questions you are unsure of to avoid negative marking.
The pattern is such-

• Physics- 60 marks
• Chemistry - 60 marks
• Biology - 60 marks
• GK and Aptitude - 20 marks

My advice to you is, besides being thorough with your CBSE syllabus (some questions come directly from NCERT), you should practise previous year AIIMS papers to get an idea of the kind of questions asked.
Good luck to you!
