The BIGGEST waste of time and money. The Facebook ad "does your 5th grader write like this (example of poorly written essay) and we can help them write like" (example of a greatly improved essay), sucked me in. 10 sessions later, my son is not writing any better. I basically paid $200 in sessions for help with his research paper and it at a C grade at best. Save yourself the time, money and frustration.

I lost 3 classes and it never got…
I lost 3 classes and it never got rescheduled. Teacher canceled the classes and it was at the end of session. Since it was canceled by class up, i thought it will be rescheduled by them. But relationship manager calls and say I have to book next session (12 classes) to get that 3 classes otherwise I’ll lose. I raised complaint, but they didn’t address my issue. They don’t care as you pay all up front. I don’t recommend class up.

Very Unprofessional; They Don't Care That You Have Unused Credits
When they're trying to get you to enroll, they're good.... Once you gave notice, good luck getting anyone to help you with an issue - even if they caused the issue. My son's teacher cancelled on us (but ClassUp kept billing us); trying to re-schedule and get a new teacher is such a hassle. We still have class credits left but I can no longer schedule a make-up class to recover my payment (acct. has been de-activated). CS is not able to do anything. I called numerous time & was told each time that a Mgr or Learning Partner will call but still nothing. Very unprofessional, not to mention they don't care that they owe you refunds. I would stay away from ClassUp.

Hi there, we do care about every customer's feedback. For teachers' cancellation we do provide sub-teachers for teacher cancelled classes since some cancellations can be unavoidable. In order to follow up with your frustration, would you mind leaving your contact with us? So that we can investigate better. Thank you and sorry for any dissatisfaction.

Not Reliable-Not Trustworthy
They charge for the classes in advance. They promptly follow up with you until you sign up, pay for the classes and trap you.
The classes are canceled without heads up, they never get rescheduled and they ask you to pay for the rescheduled classes saying the subscription was only these many weeks. They are not flexible and do not have a single teacher assigned for all sessions. They schedule and cancel classes as they wish. They do not follow up to reschedule cancelled sessions and stop answering calls, they don’t reply to emails or messages. The customer support is horrible. The company seems to be fraud who are just after money.
UPDATE TO THE REPLY FROM CLASSUP: Every few sessions, a new teacher is assigned, time is wasted with introductions and there is no continuity from previous classes/sessions. Random teacher joins, random topics are discussed. No value add.

Hi there! We are so sorry about your experience. You enrolled in a subscription, for which payment is charged every 4 or 12 weeks. You can schedule classes in the app with your remaining credits. For teachers relevant, we provide a thorough teacher support selected by our teacher operation team. Each teacher we recommended are as professional as the same. In order to ensure the study process is continuous and regular, we have back up teachers to help if your assigned teacher have to cancel a class in an unavoidable situation such as sickness. We'd love to help clear up any misunderstandings!

Don't get lured by misleading ads
Don't get lured by those false advertisements. The teaching quality nor the customer care is satisfactory. Your money is gone and there won't be any refunds. We enrolled in a 12-week elementary school writing program. However, the teacher canceled four weeks of classes in a row. Upon contacting customer service, they proposed assigning a new teacher due to the unavailability of the previous one. When we inquired about a refund for the missed classes, we were informed that transactions are deemed final, and no refunds are provided. Consequently, there seems to be no recourse for the missed sessions. For 50$ per hour, you better pay a little more and find a tutor in your neighborhood. Overall, I would never go back to this

Hi there! We are so sorry about your experience. You enrolled in a 12 week subscription. As in terms& conditions, subscription classes will expire after the 12 weeks time which also the same as the membership. We'd love to help clear up any misunderstandings!

It is very disappointing for the price …
The teacher “ Melissa” it’s AMAZING… she basically helps my son with his school homework ( ELA).. for that I can find a local help for cheaper .
Response from Cosmo (formerly ClassUp)May 7, 2024
Hi there, the price we have is to maintain the teachers like Melissa can offer the best performance continuously. As the help from Melissa is useful. Can we discuss further regarding the price issue ?

I had a horrible experience
I had a horrible experience with Classup. I enrolled my daughter, who is in high school, in AP classes for 12 weeks. However, the teacher rescheduled just one day before the class, and suddenly that schedule was not discussed with me, and the rescheduled class was not available for my daughter. It happened several times. My daughter was available to take a tutor on Saturday only because of her extracurricular activities from school. From the beginning of this tutoring, I asked to find a class on Saturday, and I registered for it. However, the teacher rescheduled it immediately for Sunday morning, which is not available. So, I wanted to reschedule for another Saturday. But Classup didn't allow me to take the classes that my daughter missed because of the teacher's changes. They said it's not allowed because of the strict policy, which states that I only have access to classes within my term. However, there is no way to take it. There are no available schedules in a week, and they don't allow me to take classes on another Saturday. I feel like it's fraud. I'm very disappointed with Classup. I recommend that people never take classes from Classup, ever.
