Yes that method would be difficult to apply.
You would need to have prepared well beforehand. Know the topic as best you can having made mind maps from your activations.
You would still get into state 3 to 1 and use the tangerine for accelerated learning. Being relaxed is important in test too. 
Since you can't expose your inner mind to the whole test you would have to do it step by step. You might try something like the following instead.
1. If you know the answer write it.
2. If you're not sure but think you know the answer ask your inner mind if it is correct - to give you your yes or no signal. (you practice with your inner mind before the test to give you signal or sensations like the green, yellow or red signals. That way you know what your inner mind is communicating better when you are sitting for a test.)
3. If you don't know the answer this is what you might do to get the answer. Since you're sitting at the computer no one will notice but I did it years ago in a regular test. Close your eyes and imagine your teacher in your mind and ask the teacher in your mind the question that you are having problems with and then let go think of something else or imagine changing channels. Then think of the question again. The answer that you inner mind produces now is usually the best answer.
If you are answering questions about a book... call upon the author in your inner mind.
The forum has often mentioned doing this in lucid dreams but you can really do that anytime, (easier with eyes closed less distraction). I can assure you it works, surprised me when I did it but got 100% on that test where I resorted to asking my teacher 3 times.
The thing you have to watch is that you don't waste time spending too long on one question. So if you use this method and an answer comes but you're not sure about it write it down anyway. An unanswered question loses more marks than an attempted one.. especially if you got it right but just weren't sure.
Let me know if you would like me to clarify any of what I said.
