<p>Yes, you can take more than 18 credits IF you are able to handle the workload. Just remember you have to pay for the extra credits beyond 18 credits that are covered by the standard tuition paid per semester. </p>
<p>Ouch! That is a lot of credits to carry. However, this depends on the individual. I can tell the OP that it will still be a lot because each course has demands. However, if one is P-F and the other is “easy,” it is up to the individual to call the situation. No one else has the individual’s pressures, motivation, and combination of personal factors to say if the OP should try it for a semester. The answer will differ depending on the person you ask.</p>
<p>Generally, it is not recommended, especially if you want to experience college not just for academic work but for ECs, social life, etc. However, I have worked with students who carried full loads PLUS. Invariably, they tell me when it is all over that it was rough and they were glad the more than full load semester was over (and wish not to do it over again). However, for some of the students, it was worth it to complete their degrees in time (or in shorter time) so they could get on with their personal and/ or professional life.</p>
