I am in 10th std, can someone tell me if I should take PCB or PCM for 11th and also, am I supposed to give JEE OR AIIMS

Well that's a tough decision to make. But may I ask you what made you think of engineering / science field as the choice of career in future? My question might add to your confusion but I have seen that more often than not, students are prejudiced towards conventional options and never give ample thought to what interests them the most or what's that they enjoy the most. I am a scientist, and ideally i shouldn't be discouraging anyone looking forward to making a career in Science and technology. But, take it as a career counselling,.before giving you any advise on what exams you should go for and what subjects you should opt for, it is extremely crucial to ascertain the level of motivation.

No decision of your life or career should be made:

1. Because, everyone else is doing the same

2. Because of compulsions

It has to be a choice, because it's about how you want to live in future.

All the best
