What is a reasonable amount of study length for an average IQ student

I have an IQ of 102 and I always wondered what amount of time is needed for someone like me to pass exams. Let's say you have an Electircal engineering exam in 3 weeks, would someone with that IQ managed to pass that if he or she studies 8 hours a day or is it impossible unless one dedicated 3 months exclusively to it?
