How I Actually Used Electricityandcircuitspracticeexam to Pass My EE Midterm
I stumbled across the Electricityandcircuitspracticeexam when I was two weeks from my circuits midterm and had barely touched anything past Kirchhoff's laws. My professor had assigned a PDF bank of problems that looked more like textbook exercises than actual exam questions. I needed something closer to what would actually be on the test. The practice exam site filled that gap, but not in the way you might expect from reading the homepage. It is a collection of practice problems covering basic DC circuits, AC analysis, network theorems, and transient response. Most free resources online are either too simplified or pulled straight from textbooks without real exam conditions. This one sits somewhere in between. The questions are structured like a standard multiple-choice and short-answer exam, and the difficulty scales as you move through sections. Some problems are straightforward Ohm's law applications. Others require you to set up nodal equations by hand before arriving at an answer. The real value is in the answer explanations, which are where most people skip. I used to just check if I was right or wrong and move on. That approach left me failing questions about Thevenin equivalents because I did not understand why a particular resistance value was correct.
How I approached it
I started by taking a single section under timed conditions. No calculator help for the easy problems. No peeking at solutions until I wrote down my final answer. The first time I did this, I scored about 58 percent. Most of my mistakes came from signing errors in nodal analysis and forgetting that dependent sources change how you handle Thevenin resistance calculations. I went back through only the problems I missed and worked through each explanation slowly. Then I retakes that section two days later. I came up to 76 percent. The method that actually works is to treat the practice exam like a diagnostic tool, not a progress tracker. You want to identify what you cannot do, not confirm what you already know. I spent more time on problems I got wrong than on the ones I got right, and that is where the score improvements happened.
A specific problem I ran into
There was a question involving a circuit with two voltage sources and a load resistor that asked for the power delivered to the load using superposition. I applied superposition correctly for the voltages but forgot to turn off the current through the middle branch properly. I treated one source as a short and left the other resistor open, which is backwards. The answer key explanation walked through the correct deactivation step, but I still got it wrong on my first pass. My workaround was to redraw the circuit on paper, label every node, and physically cross out the inactive source instead of relying on mental visualization. That visual step cut my error rate on superposition problems significantly. One thing that caught me off guard was how often the exam tests your ability to estimate before calculating. There is a section where you have to pick the closest answer without solving the full equation. My instinct was to always compute the exact value. That wastes time and sometimes introduces rounding errors. Learning to bound the answer using simple mental checks, like seeing whether a voltage divider result must fall between two known node voltages, saved me roughly ten minutes on a 90-minute exam. I wish I had practiced estimation earlier. Another issue is that people rely too heavily on simulation tools before attempting hand calculations. I used SPICE for verification while studying, but when the actual exam arrived, I had to solve things on paper with no tool to fall back on. The practice exam helped because it forces hand work first, then you can use simulations only after. That order matters.
Where it falls short
The Electricityandcircuitspracticeexam does not cover advanced topics well. If your course goes into Laplace transforms for transient analysis, controlled source design problems, or frequency domain filter synthesis, you will find gaps. The AC section stops at basic phasor analysis. It also repeats some problem types verbatim across different versions, so if you reuse the same set too many times, you may memorize answers instead of learning concepts. For students who need deeper coverage, I recommend pairing this resource with a textbook problem set and a few past papers from your own department. Those will fill in the missing advanced material. There is no single practice exam that covers everything, and pretending otherwise just sets you up for surprises on test day.
Practical tips for using it effectively
Set a timer for each section and stick to it. If you spend more than five minutes on a single problem without making progress, mark it and move on. Come back later. Do not let one stubborn question drain your confidence for the rest of the exam. Track your weak areas explicitly. Write down the topic of every problem you miss. After three sessions, you should see a pattern. For me, it was dependent sources and mesh analysis with current sources. I then focused additional review time on those topics before the next practice run. Use the explanation sections actively. Read the solution only after you have committed to an answer and written down your reasoning. If your reasoning is wrong, the explanation will show you exactly where your logic diverged. That divergence point is where real learning happens.
Do not take the entire exam in one sitting unless you are simulating actual test conditions. Breaking it into sections reduces fatigue and gives you cleaner data about which topics you still need work on. A full sit-down at the end, two days before the real exam, is useful for building stamina and pacing, but doing all the practice in one go tends to blur your memory of which questions tripped you up.
Download and access
The main Electricityandcircuitspracticeexam resource is available through the original practice exam site. I downloaded the latest PDF version and printed it out rather than working on screen, because writing by hand reduced distractions and matched actual exam conditions more closely. The file is updated periodically, so check the revision date to make sure you are working from the current set. If you want quick access without creating an account, the direct download page lists the most recent version along with a separate answer key document. Keep both together so you can cross-reference problems efficiently.
Final thoughts
This resource will not make you an expert overnight, and it is not designed to replace proper coursework. It is a targeted practice tool that works best when you use it honestly. Take it seriously, review mistakes deliberately, and supplement it with additional material for topics it does not cover well. That combination is what pushed my scores from average to solid over a few weeks of focused study. Most people underestimate how much the practice exam can reveal about their actual understanding until they sit down and attempt it under realistic conditions. Once you do that, the gaps become obvious, and you can address them before the real exam arrives.
