Yes, written in the mid-1970's when computers were still delicate, gargantuan machines that had to be carefully used and often malfunctioned. And the story of Conte Mark, through a computer error, being identified as both Conte Mark (his actual name) and Mark Conte in the high school class list decides that, instead of going to the school administration to correct the mistake, decides to take a double load of classes under both identities and graduate two years early.
How does he do this? He had previously been found to be a boy with advanced mental capabilities, so not only is he able to study extra, but he convinces several people to help him, including some to impersonate him in certain classes. Another method is for him to choose classes where he doesn't have to be around the whole time, and to use the same work in one class to complete assignments in another class, such as a biography on a scientist to be used both in English and science classes. Even then, things often go wrong through misfortune and miscalculation, and he has to devise alternate plans, but Conte Mark is no Gary Stu-he sometimes screws things up himself and has to depend on others to make things work, as well as to come up with ideas when he runs dry.
Why does he do this? He is unhappy at being forced to move to a new city when his father is fired from his job, and intends to graduate from high school early with the dream of going to the University of Chicago at sixteen, namely because he wants out of this city. Ultimately, things do not turn out exactly as intended.
The book has plenty of satire of the era, from an environmental march creating a huge mess the city has to clean up, to the idea of a pyramid supposedly causing all sorts of miracles, Forget Watergate or the AMC Pacer; this is what you want to read to get the true spirit of the 1970's.
