How to Turn Missed NEC Practice Questions Into a Digital Study Plan

You’ve just done another practice exam, and the score is pretty much the same as last week. You go through the incorrect answers, give a few of them a nod, and close the app; start another test tomorrow. A month on and you’re still missing the same sorts of questions.

Missed questions are by far the most useful bit of a practice exam as they pinpoint precisely where your code knowledge is lacking. A simple digital study plan can then be used to take that list of missed questions and turn it into a series of focused review sessions that actually lead to an improved score rather than just going over the same material again.

Step 1 – List Every Missed Question in One Place

Start by taking all the questions you missed on your most recent practice tests and putting them into one master list. It’s a lot harder to see the pattern when the questions are scattered across a number of test results.

A simple spreadsheet or notes app will do. For each question you’ve got wrong, just log the date, the topic, the answer you selected and the correct answer. If your practice tool provides you with the code reference for the correct answer, then include that too.

Go back to your last 3 or 4 practice tests (not just the most recent one). One test won’t give you the full picture but three will usually tell you which topics you’re consistently missing.

Step 2 – Group Missed Questions by Topic

When you group by topic you go from a long list of mistakes to a short list of things to study. Just add a topic column to your list and sort by that.

Use broad groups that correspond to the way the code is structured and the way your exam is weighted. For electrical exam candidates, the typical groups would be:

• Grounding and bonding
• Conductor sizing and ampacity
• Box and conduit fill
• Motors and motor circuits
• Load calculations

Count the missed questions in each group, then rank your topics by how often you miss them. The two or three topics at the top are where your next few weeks of study should go.

Step 3 – Work Out Why You Missed Each Question

Knowing why you got a question wrong is just as important as knowing the topic. Each type of mistake requires a different remedy so add a ‘why’ column alongside the topic.

Most of the questions that were missed fall into one of three categories.

You Couldn’t Find It in the Code

If you knew the subject but were running out of time searching, then the problem is navigation. Just get used to being able to find the right article and table quickly and make use of the index.

You Misread the Question

If the answer was there but you’d missed a word (e.g. ‘minimum’, ‘except’, ‘not’) then slow down. Underline or note the key words in every practice question until careful reading is a habit.

You Made a Calculation Error

If you’ve set up the problem correctly but made a maths error, try reworking a couple of similar problems by hand. Just write out each step so you can see precisely where the error is.

Step 4 – Keep Short Digital Notes for Each Topic

Short notes will help you to remember what you’ve learned and digital notes are easy to search and easy to keep on your phone. Write one short note for each topic on your list, not a rewritten chapter of the code.

Each note should have the rule in your own words, the code reference you’d go to, and one example question you missed. Keep the notes to a few lines only so you can read them during a break at work or before a practice session.

A notes app you already use is usually the best choice, because you’ll actually open it. If you want a simple option with labels and reminders, here are some things you can do with Google Keep that suit quick study notes.

Step 5 – Schedule Focused Review Sessions

Short focused sessions on one topic are far better than long sessions that attempt to cover it all. Just book them on your calendar like any other appointment and you’ll be far more likely to actually turn up even in the busiest of weeks.

Plan to come back to each topic more than once. A practice guide from the Institute of Education Sciences recommends that learners space learning over time, reviewing key material again after a delay. A weekly plan might look like this:

• Two 30-minute sessions on your top-ranked topic
• One 30-minute session on your second topic
• One short session rereading last week’s notes
• One timed practice set at the end of the week

Protect your review time by picking sessions you can realistically keep. Three sessions you finish beat six you skip.

Step 6 – Retest and Update Your Plan

Retesting will tell you whether your review sessions are actually working so do include it in your plan on a weekly or bi-weekly basis. Take a fresh practice set on the material you’ve been studying and then update your list with any new questions you’ve missed.

Use a practice tool that makes reviewing mistakes easy. With NEC exam practice from Dakota Prep, you can choose to see only the incorrect answers when you review a past exam, which makes it quicker to pull new misses into your list. Compare each new result with your earlier counts, topic by topic, before you decide what to study next.

When a topic is near the bottom of your list, just move on to the next one and review that. Keep one or two of the topics you’ve finished in your practice sets so they don’t go cold and are still fresh in your memory until exam day.

Sort Your Last Three Practice Tests Tonight

A practice score will only tell you where you are. Your missed questions will tell you what to do.

Tonight, open your last three practice tests and list every missed question with its topic. By the end of the evening, you’ll know which two topics deserve your next week of study.

Frequently Asked Questions

How do I decide what to study for the NEC exam?

List your missed practice questions, group them by topic, and count the number of misses in each group. Prioritize the two or three topics that you’re missing most.

How long should NEC study sessions be?

Short, focused sessions of around 30 minutes on one topic are generally the way to go for the majority of candidates. Book them on your calendar and come back to each topic more than once.

Why do I keep missing the same NEC practice questions?

Work out whether you just couldn’t find the answer in the code, whether you misread the question or whether you simply made a calculation error. Each of those scenarios requires a different approach to the fix (index practice in the first case, reworking the problem by hand in the latter).
