fortinet training

I recently completed fcf and fca certificates and im looking into to doing one of the following fcp certifcates but it looks somewhat overwhelming, looking to find any practice or lessons that involve nse 4 os training but cant find it on the fortinettraining portal. Is there any advice I can get for preparing for it when i schedule an exam or any tips to further progress in the program. For reference im in college just finding something else to learn while im on break or when not alot of work related to college.
