Exams are used to measure your ability to, memorise, understand, use logic, be creative, think fast etc.
Basically, the system wants to sort out the smart students from the dumb ones. You can't try to be smart, you're either smart, or you're not.
If you want to ace your exams then just get smarter, plain and simple.
I'm naturally smart because I've got a pleiotropic gene mutation, and excess white matter in my brain, due to aspergers syndrome.
Your brain is made up of neurons, and white matter. Neurons communicate via synapses. Let's make an analogy, the neurons are the thinking power, the white matter is the motherboard/chipset, and the synapses are the communication bus.
If you want a faster PC with more thinking power, then you upgrade the CPU or overclock. Upgrade the chipset or overclock, and overclock the comm bus/timings.
So how do we get smarter? I say, Nootropics/drugs/medication.
You can increase the number of neurons in your brain by enhancing neurogenesis. Pregnenolone, CREB modulators, cAMP enhancers, etc can increase neurogenesis.
Next up, white matter. Beta catenin/WNT activation via sex steroids (testosterone/oestrogen) can increase white matter in your brain potently, hence the reason why people experience an increase in cognition during puberty.
Increasing synapse effiency is the hardest because it's not something you can do permanently. Piracetam and aniracetam, along with other nootropics can enhance synpase functioning allowing your neurons to communicate faster, and with more effiency. More neurons talking to each other = more brainpower.
