I'm doing an electromagnetic fields and waves course. The first part of the course was mainly about transmission line's, using the Smith chart and a host of equations that comes with transmission lines...we had a mid semester exam and i got 13/30, which i wasn't happy about but i didn't put in as much study time as i should have so i wasn't surprised. Now i'm wondering whether i should drop the course? The second part is now focusing on Maxwell's equations, so we're getting into the actual electromagnetic fields and waves part of the course, which i'm finding kinda tricky but i'm able to grasp it if i put in extra time to study the material. However i know of one guy who did the course last year, he also failed the mid semester exam and ended up failing the course all together, i'm kinda worried that i'll end up in that position since i've also heard of other people who have failed the course. So this leads me to the whole point of my post, should i drop this subject? Better not to take the risk? Or get myself into it more vigorously and make sure i pass the final exam (which is out of 60% btw, and our tutes correspond to 10%, which i know i'll get). I'd like to take an antenna related course after this one, so i kinda do need to stay in it but i still don't know if i should take the 'risk'. Plus the other thing is, is that I would have liked to get a high grade for this course..it's still possible i guess, so long as i study extra hard for the final exam..
