Simple answer... yes you can.
Though are you likely to succeed in accurately recording what you see without any former experience? Absolutely not.
If you were trying to view some documents I would highly recommend remote viewing over astral projection. It's not so simple though. You have to commit to it. It takes time & practice to be good with these things.
With AP you may forget a few things. With RV you would not forget, you record the data as you are projecting. Though you would have to be experienced & good enough to see the documents clearly in detail to begin with.
No you will not be caught on camera with either AP or RV. Cameras can't pick up conscious minds that project their awareness.
There is no magic product on the net that will guarantee you success. Don't believe anyone selling some crap on the net promising you success in AP or whatever. These people are not interested in your success, they are only interested in their success. That is their financial success. There's a sucker born every minute. Don't be one of them. Success comes in time with practice, education & dedication. There are no short cuts, period!
Why would you want to cheat in exams anyway? Tests are there for you to learn & grow. Cheating is for the weak minded. That is the easy way out, but not a wise option.
