Registering for exams online is convenient, but it has pitfalls. If you confuse the module with the exam itself, overlook a deadline or never check the confirmation, you can end up without an exam place. This guide shows the typical mistakes in online exam registration (Prüfungsanmeldung) and gives you a checklist to avoid them.
Short answer: Online registration usually fails because the module and the exam are not both registered, deadlines are missed, or the confirmation is never checked. At TU Dresden, you can withdraw until three working days before the exam date (rule in force since the 2024/25 winter semester, retrieved November 2026). The exact steps at your university are set out in the exam portal and in your examination regulations.
The most important points at a glance
- Register not only for the module but also for the examination performance, if your portal asks for both separately.
- Check the registration window, because a deadline falling on a weekend does not move automatically in your head.
- After registering, confirm in the portal that the status really says registered.
- Know the withdrawal deadline, which is often shorter than the registration deadline.
- Keep screenshots and confirmations until the grade appears in the system.
Which mistakes do students make most often?
The mistakes are rarely spectacular, but they have a large impact. The portal may accept a registration in form, yet the admission is still missing. Conversely, a registration can arrive too late even though it was sent in time technically. The table below classifies the most common errors.
| Mistake | Typical consequence | How to avoid it |
|---|---|---|
| Only the module registered, exam performance forgotten | Exam does not take place or is not graded | Check both steps in the portal separately |
| Deadline on a weekend overlooked | Registration arrives too late | Enter the deadline in your calendar with a buffer |
| Withdrawal deadline missed | The attempt counts even though you do not sit the exam | Note the withdrawal deadline separately |
| No check after submitting | Errors stay unnoticed for months | Check the status again one day later |
| Withdrawal without form or medical certificate | The exam is treated as not passed | Submit the form and evidence immediately |
| Confusing study achievement and exam performance | Wrong expectations about registration or grading | Read the module handbook, see article below |
The confusion between module and exam is usually the most costly. One university example shows how it can work: first you register for the module, then for the examination performance. Whether your degree programme works exactly this way is set out in the guidance of your examination office.
How does registration work in one example?
This example comes from TU Dresden, not from your university. At TU Dresden, registration takes place online through the Selma portal of the examination administration. If you cannot register there, you submit a signed registration form at the examination office within the registration period. If the end of that period falls on a weekend or public holiday, registration ends on the next working day. A missed registration can only be made up on a justified written application to the examination committee.
These steps show what to look out for. Whether a portal confirms a registration immediately, whether a form is needed and how deadlines are calculated differ between universities. It is therefore worth reading the guidance of your examination office before the registration window opens.
How do you avoid the withdrawal trap?
Many students think registration is the most important step. In practice, withdrawal matters just as much, because it decides whether an attempt counts. In the TU Dresden example, you can withdraw in Selma up to three working days before the exam date. For oral exams without a fixed date, an informal written application at the examination office is enough. For portfolio exams and project, home and seminar papers, withdrawal ends with the end of the registration period.
If you want to withdraw, do not treat the deadline as a formality. A late withdrawal can mean that the attempt is counted even though you did not sit the exam. A separate article explains the consequences for attempts and repeats: Modulprüfung wiederholen: Wie oft du im Studium antreten darfst (in German).
What applies if you fall ill and cannot sit the exam?
Withdrawal is a separate procedure, not the same as deregistration. The TU Dresden example requires a mandatory form, “Rücktritt von Prüfungen”, and a medical certificate for illness-related inability to sit the exam. The originals must reach the examination office without delay and within three working days. For a withdrawal after the exam has started, the supervising staff should be informed immediately, followed by the examination office. The page does not name a fixed number of days for the next step, so speed is essential.
Document technical problems as well. A screenshot with a time stamp, an error message or an email to support are valuable evidence if you later need to explain why a registration failed.
Checklist for your registration
- Read the registration window of your degree programme and enter its start and end with a buffer in your calendar.
- Register for the module, then check whether the examination performance also appears in the portal.
- Check the status one day after registering and take a screenshot.
- Note the withdrawal deadline and set a reminder two working days before it.
- Keep all confirmations, forms and evidence until the grade is recorded.
Frequently asked questions
What happens if I registered too late?
In the TU Dresden example, a late registration is possible only on a justified written application to the examination committee. The committee decides whether the reason is sufficient. Apply early and attach evidence.
Is a registration in the portal always enough?
Not necessarily. In the example, a signed form can replace the portal registration if the portal does not work. What matters is that you act within the registration period. If in doubt, ask the examination office which route applies.
What is the difference between withdrawing and an illness-related withdrawal?
When you withdraw before the exam, you step back before the date and no attempt is used, provided you keep the deadline. An illness-related withdrawal means you do not appear or stop during the exam, and you must document the reason. The consequences differ considerably.
Does the deadline also apply on public holidays?
In the TU Dresden example, the registration period ends on the next working day if its end falls on a weekend or public holiday. Whether this also applies to withdrawal is usually set out in your regulations. Do not rely on it. Plan with the working day before the holiday.
So what should you do now?
- Open the exam portal of your university and look up the registration deadlines for the coming semester.
- Compare the registration steps with the checklist above and note any differences.
- Register, check the status and keep the proof.
- Clarify open questions about withdrawal and deregistration with the examination office early.
