Thats low but there is a lot of debate around its validity and what its measuring. One thing to keep in mind are the scores are normalized and age can be a big factor. Its general intelligence so your likely to have the best score when you just finished up your broad education. So like second half of college maybe in the summer so it would not take away from your studies. Once you stop regularly studying a liberal arts style education you are likely not to do as well as your brain is mostly split involved between whatever your career is about, whatever you need to do for your lifestyle day to day, and whatever your interests are after that.
