Thermometer is a good idea, but if you are using a home oven, is important to read the instructions of your oven, some of them have recomendations where to put things acording what you are baking.  At diferent levels diferent temperatures for some ovens.   I reallly have battled with the oven brands here in my city, because I have had problems with a pair of brands and today ovens are made ´for people that don't bake,, only to show a beautiful kitchen, so the brands are not takeing care of the oven.   But there are a few like me that uses it often.
