Why Registration Matters More Than You Think

Choosing the right classes can make or break your semester. The wrong professor can turn an easy class into a nightmare. A bad schedule can leave you exhausted or with awkward gaps. Missing a prerequisite can delay your graduation by a whole semester.

Registration is a skill — and once you learn it, your college experience gets dramatically better.

Step 1: Meet With Your Advisor

Before registration opens, schedule a meeting with your academic advisor. They can help you:

• Understand which classes you need for your major
• Identify prerequisites you might be missing
• Plan your course sequence (some classes are only offered certain semesters)
• Make sure you're on track to graduate on time

Bring a draft schedule to the meeting. Your advisor will refine it.

Step 2: Research Your Professors

Not all sections of the same course are equal. The professor makes a HUGE difference. Research them before choosing:

RateMyProfessors.com

• Check overall rating (aim for 3.5+ out of 5)
• Read the actual reviews (some low ratings are from students who didn't show up)
• Look for mentions of: clear lectures, fair grading, helpful office hours, heavy workload, unclear expectations
• Check the "difficulty" rating — a 3.5 difficulty doesn't mean bad, it means challenging

Other Sources

• Ask upperclassmen in your major
• Check if the professor has a website or YouTube channel (some post lecture materials)
• Look at the syllabus if it's available in advance

Step 3: Build Your Schedule

Consider These Factors:

Time of day: Are you a morning person or a night owl? Don't take 8 AM classes if you know you'll skip them.

Spacing: Back-to-back classes mean no travel breaks. Big gaps mean wasted time on campus. Find a balance.

Workload balance: Don't schedule all your hard classes in one semester and all your easy ones in another. Spread the difficulty.

Days: Some students prefer classes every day (MWF schedule). Others prefer condensed schedules (Tu/Th only). Consider what works for your learning style and other commitments.

Build 2-3 Backup Schedules

Popular classes fill fast. If your first choice is full, you need alternatives. Plan:

• Schedule A: Your ideal schedule
• Schedule B: Same classes, different professors or times
• Schedule C: Alternative classes if your top picks are full

Step 4: Know Your Prerequisites

Prerequisites are classes you must complete BEFORE enrolling in another class. Examples:

• English Comp 1 before English Comp 2
• Calculus 1 before Calculus 2
• General Chemistry before Organic Chemistry

If you try to register for a class without the prerequisite, the system will block you. Check prerequisites in your school's course catalog BEFORE registration day.

Step 5: Register Fast

Registration typically opens on a specific date and time based on your class standing (seniors first, then juniors, etc.). When your time slot opens:

1. Log into your registration system at least 5 minutes early
2. Have your course numbers (CRNs) written down or copied
3. Add all your classes immediately — don't browse
4. Check for conflicts or errors
5. Confirm your schedule

This process should take less than 5 minutes if you're prepared. Students who browse during their registration window often find their top classes are full by the time they're ready.

What to Do When a Class Is Full

Waitlist

Many schools have waitlists. Sign up for the waitlist — students drop and add classes during the first week, and you might get in.

Check During Add/Drop Week

The first 1-2 weeks of the semester usually have an "add/drop" period where students can change their schedules. Classes that were full often open up as students drop.

Talk to the Professor

If a class is full, email the professor:

"Hi Professor [Name], I'm very interested in your [course name] class but it's currently full. Would it be possible to get an override or be added if a spot opens? I'm on the waitlist."

Some professors can override enrollment caps for motivated students.

Take It Next Semester

If you absolutely can't get in, plan to take it the following semester. Adjust your schedule accordingly and move on. One delayed class isn't the end of the world.

How Many Credits Should You Take?

• Full-time: 12-18 credits per semester (usually 4-6 classes)
• Recommended for most students: 15 credits (5 classes)
• If working part-time: 12-13 credits (4 classes)
• To graduate in 4 years: Average 15 credits per semester

Taking fewer than 12 credits may affect your financial aid, housing eligibility, or insurance. Check with your school.

Registration Mistakes to Avoid

1. Not checking prerequisites — You'll be blocked or forcibly dropped
2. Ignoring professor reviews — A great class with a terrible professor is a terrible class
3. Taking too many hard classes at once — Spread your difficult courses across semesters
4. Not having backup plans — Your first-choice schedule rarely survives contact with reality
5. Registering late — Every minute counts during registration windows
6. Forgetting to actually click "confirm" — Check your schedule after registering
