Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits. Educational methods include storytelling, discussion, teaching, training, and directed research. Education frequently takes place under the guidance of educators, however learners may also educate themselves.
If the exam team allows the students to do so, then it is permissible, but if they do not allow it, then it becomes a type of cheating which every Muslim must avoid.

You are not too old; as the hadith says, "Seek knowledge from the cradle to the grave." Besides, many Islamic scholars started their education later.
There are physical colleges that you can attend and also there are a number of online courses; you can explore them to see what fits your needs.
