My experience was similar to shortys. Definitely take a break and eat a snack if you need to, but do whatever works for you. I powered through with no breaks, but I am the type of person who just wants to get it done. If you have to travel to a testing center (the closest location to my school was an hour away, which is silly, maybe itās more widely available now), going down the night before may be worth the expense to avoid any travel related delays or having to get up extra early.
I found the ICVA assessments to be useful, I did one a couple weeks before the exam so I knew where to focus the last few weeks of studying. I donāt know that taking one right at the end does much imoā¦if you do great it may increase your confidence but if you take one a day or two before the exam and donāt do great thereās no time to improve and it just stresses people out.
Remember that the vast majority of people walk out feeling like they did poorly. If you leave feeling great, thatās great. But despite everyone being warned, itās almost a near-universal experience of people leaving thinking it was harder than they expected. But the vast majority of people pass.
