I would like to create a free profile on OpenProf. How do I do this?
 
OpenProf users can create a user profile that is entirely free of charge. To do this, you must first select your registration form. To do this, click on the "User login" link at the top right and then choose your entry point:
 

Then you have the following options:
 
  • Registration by email: A form will open to enter your username (email) and password. Select “Not registered yet?” At the bottom of the form. You will be shown a registration form to fill out. Then go to your mailbox, where you will receive a confirmation email to confirm your username.

Students and parents have two additional options (which are extremely practical):
 
  • Sign in with Google: If you want to sign in to OpenProf in the future via your Gmail profile, you can create your OpenProf profile by simply clicking on the red button labelled “Sign in with Google” and follow the instructions
  • Sign in with Facebook: If you want to sign in to OpenProf in the future via your Facebook profile, you can create your OpenProf profile by simply clicking on the blue button labelled “Sign in with Facebook” and follow the instructions.

Important: When checking your email, always check for spam or promotional tabs (such as in Gmail).


How can I sign in to my existing OpenProf profile?
 
If you have a profile created on OpenProf, you also have a username. Your username has the form of an email, e.g. donald.duck@gmail.com. You can only access your profile if you know your username.

Sign in to your profile by clicking the “User login” link at the top right of the page and then selecting your entry point:
 

There are different ways to sign. You can choose between:
 
  • Sign in with your email:
     
    • A form for entering username and password will open;
    • Enter your username and password.
    In case you forgot your password follow the instructions here.
     
  • Sign in without a password:
    • Enter your username;
    • Open your email inbox, where the email with instructions will arrive.
!! When checking your email, always check for spam or promotional tabs (such as in Gmail).

Profiles for students and parents have two additional options:
 
  • Sign in with Google
     
    If your username is Gmail, you can simply click the red button “Sign in with Google” and follow the instructions if you’re signed in to your Gmail profile. Sign-in will happen automatically.
     
  • Sign in with Facebook
     
    If you have your Facebook profile and this profile is created with the same address as your OpenProf username, you can, just like with a Google account, simply click on the blue button “Sign in with Facebook” and follow the instructions. Sign-in will happen automatically.


My profile is not confirmed. How can I confirm it?
 
The moment you registered for OpenProf, we sent you an email with a link to the instructions. First, confirm your profile by clicking on the link you received. This confirms the identity of your email address, which is important for several reasons – including being able to regain control of your profile if you lose your password.

What to do if you have not received an email? The solutions are:
  • The email has arrived, but it has been marked as spam, which means it’s in one of the auxiliary folders of your email application. So, please check to see if the message might not be in one of the folders like: “Bin”, “Spam”, “Junk”, etc.
    Then check the auxiliary folders, which can vary considerably from provider to provider. For example, in the case of Gmail users, please check folders like “Promotions”, “Social”, etc.
    If our message did land in the junk mail, please mark the message as “not spam”. This will prevent similar complications in the future.
  • You may have entered an incorrect email address when registering. In this case, go on your own profile page and make sure you write down your email address without mistakes. If your email is misspelt, correct it. As soon as you save the corrected email, you will receive a new confirmation message containing a confirmation link.
 
If you registered with OpenProf some time ago and do not have your account confirmed yet, go to your profile page, alter your email address and save it. Then correct it again, save the correctly spelt one – and you will receive a new confirmation message.


I forgot my password, what can I do?
 
You can start the process of issuing a new password at the following links:
 
 
!! When checking your mail, always also check your spam or promotions tabs (such as in gmail).
 
 
You can also access the link as follows: when choosing the registration method, select the dark blue button "Sign in with e-mail" and the registration form will appear. In the lower part of the form there is a link "Forgot your password?". You click on the link and follow the instructions.


How can I change my username?
 
To change your username, you must first log in to your profile and then make the change at the address: Your username is the same as your email address, so you change the field "Username (email address) ".
 
 
!! The new username can only be an e-mail address that does not yet exist in our database. In case of input of an existing e-mail address, the system will reject your change, as a profile with an existing e-mail address already exists.


How can I delete myself from OpenProf?
 
OpenProf allows complete and irreversible deletion. To delete yourself, please follow these steps: Then follow the instructions. But beware: the deletion is complete, which means that with the deletion, you also lose all possible privileges, such as, e.g. access to paid content.


Which content does OpenProf offer for free, and which content is paid for?
 
OpenProf is a comprehensive and free replacement for (paid) textbooks. Namely, everything that paid textbooks offer for the existing subjects can be found free of charge on the OpenProf platform. For full access to free content, you only need to create a (free) user profile, and you can (freely) access all theories, problems and final solutions of the problems.
Paid content is limited to detailed step-by-step solutions that OpenProf tutorials are equipped with. Detailed step-by-step solutions allow you to learn faster and more efficiently, even to the extent that we at OpenProf are ready to refund your paid subscription if you do not raise your grade at school. More on this in the price list.


I unlocked access to the problems via SMS. Will you charge me for that?
 
We build OpenProf on a clear, transparent and fair relationship. Therefore, SMS unlocking, as it says, is completely, utterly and entirely free of charge. This, of course, excludes any hidden commitments, small print and other incorrect practices.


Can you charge me for access without my direct consent?
 
In short: NO. At OpenProf, every transaction occurs solely and exclusively with the direct and conscious consent of the user to the transaction.
A slightly longer answer is: we are building the OpenProf platform according to the highest ethical standards, with a strong emphasis on transparent operation, which is for the benefit of the end-user. Therefore, on OpenProf you will not find any hidden or misleading texts, various dubious approaches (such as “SMS clubs”), etc. In this spirit, subscriptions are also regulated so that they are not executed automatically, but users must confirm each transaction separately, which means that all transactions occur with the full awareness of our customers.


I would like to pay a subscription – when will I be able to access the premium content?
 
The OpenProf subscription for access to step-by-step solutions can be paid in three ways:
  • By online payment directly using a credit card;
  • By payment via PayPal;
  • By a PDF proforma invoice.
 
In the case of payment by a credit card or via PayPal, you receive access to paid content the moment you finish the payment process, and you can start using the system right away.
 
In the case of settling a PDF proforma invoice (e.g. with a transaction through an online bank), the procedure takes some more time, as the bank must first transfer the funds to an OpenProf account, which can take up to several hours. It should be taken into account that the bank transfers funds only during working days and until 4 pm. If you settle the proforma invoice after 4 pm, the funds will not arrive in the OpenProf account until the next day (or the first following working day).
 
As soon as we receive the funds in our bank account, we record the payment and provide access. We check new payments on OpenProf several times a day.


After paying the subscription: what do I gain access to, and how can I access the step-by-step solutions?
 
When paying the subscription, you can only decide on the duration of the subscription (1 month, 3 months, 12 months, etc.), but not what you can access. This is because all subscriptions offer access to everything: all subjects, all grades, all step-by-step solutions... in short, all the content offered by OpenProf.
After paying the subscription, the method of accessing the content does not change: you continue to view the content signed in to your OpenProf profile. When paying by credit card or via PayPal, this access activates immediately after successful payment. In case of payment through a PDF proforma invoice, we activate your access manually – and we will also notify you by email within one working day at the latest.


Problems in PDF are slightly different from online problems. Why?
 
For some tutorials, when you export them to PDF, they may be slightly different from the ones you see online. If you look more closely, the problems are actually the same, only the numbers in the problems differ. This is done on purpose, but this (unfortunately) only applies to a small part of the problems.
 
The reason the numbers differ is as follows. Each problem has its own content (e.g. what problem it addresses, how it addresses it, how it solves it, etc.) and its form (e.g. it doesn’t matter whether the person appearing in the problem is called Mary or Jane, or if multiplication is done by 2 or 3). Because we want to teach children with our problems mainly the content (and not the form), we have programmed some of the problems by changing the form – not the content.
 
Namely, sometimes it happens that when a child solves one problem if we offer him or her the same problem (with the same numbers), the child will solve the problem from memory when solving it – which is not right. Programmed problems change form (but are always solved in the same way) so that the child can test himself or herself in the right understanding of solving the problem and avoid repeating from memory.
