The worst thing about high school is that they don't teach you how to apply the material you learn. The subject matters and instruction materials are great, but I think a lot of students get really bored and that is just as useful as teaching someone to retain the material for 15 minutes, from the time they step out of the classroom it's considered short memory. If you can apply the principle with the material, then you get the students to engage into thinking how do I apply what I learn to real world applications.
The worst thing about Coastline is that in my base, Camp Pendleton, they don't offer any on base classes. All the classes I have to take therefore have to be online because there is no staff that is located on base. I prefer to learn by physically interacting with the teachers and asking questions in class. I definitely wouldn't have any dislikes about the school if they addressed this issue for military personnel looking for off duty education on Camp Pendleton.
