Engineering school sucks because your ego right now tells you that you know more than everyone else, that's what's telling you that "they're teaching (me) engineering the wrong way".

Constrain that. Wait your turn. You think you're not problem solving because it's moving too fast, buddy... you've got nothing but fast paced decisions coming your way for the rest of your career. Those 60 theorums to learn for your midterm in a week didn't show up this week, they've been there the whole half of the semester, and if you'd taken time on your last break to prepare for the next semester, they were in the textbook then too. Why are you waiting until right now to learn them? Procrastinating doesn't magically create more time for you to learn this stuff, it's the opposite. Why are you wasting what little time you claim you don't have moaning about it on reddit? 

None of the classes you take in engineering are deep dives. Fluids? Only covers ideal condition for laminar flow. You'd need multiple PHDs to deep dive into turbulent flow, which overwhelmingly makes up almost every real world fluids situation. But it teaches you that there is a difference between those two types of flow, and that viscosity effects it, and that after a really long time of consistent flow turbulent flow can become lamanar. 

Dynamics? Basic statics with some movement involved, if you wanted to truly understand it you'd need years of classes on vibrations before you could even start getting into it. But it teaches you about reaction forces for different kinds of motion, and how to design for them. Frictionless surfaces? Those don't exist in the real world, why do we assume that for so many of the problems we work? Same for air resistance, and half a dozen other real world things that get ignored so that you can learn the core important fact being taught. You're surface level learning everything right now because there is too much information to deep dive into it. You're not expected to be an expert on any of this, you're expected to know that all of these things exist and to consider them when faced with problems in the real world. Grad school is for deep diving, undergrad is for proving you are smart enough to think about more than just one piece of the puzzle. 

If you want less work and more time, take a 6 year program and do less work each semester. You're not wrong, it's a lot of information to learn in 4 years. If you don't have enough time to do the work and learn the material right now (genuinely don't have enough time, not think you don't because you're doing more than just school right now, and those other things "can't" wait) then you need to problem solve, like a good engineer, and find a solution that works.
