Manage your time wisely as you study. Cover all the basic concepts before delving too deeply into any one topic. If you have a specific question, you can e-mail me at albi.romero@cabrillo.edu
I will reply to e-mails several times the night before an exam. Continue to study other topics while you wait for a response.
