Cosmo (formerly ClassUp) Arvostelua 

I am writing to express my deep dissatisfaction with your platform. Having used several online and in-person tutoring services over the years, I can say with confidence that this has been the most disappointing experience to date.

Your sales process was incredibly aggressive—pushing us to sign up quickly with promises of results, personalized attention, and an advanced AI-powered experience. Unfortunately, what has followed has been anything but.

The platform itself is poorly designed and unintuitive. The quality of instruction has been subpar, and there seems to be little thought given to actual educational outcomes. Your use of AI feels more like a marketing gimmick than a helpful tool—it lacks the intelligence, adaptability, and relevance needed to support meaningful learning.

Worse still, your system for matching students with the right instructors has been chaotic. Despite claims of limited availability, nearly every time slot appears open—yet we’re told to rush to book. There is also a significant language and communication barrier that has made it nearly impossible to get clarity or support.

Overall, the service lacks direction, consistency, and credibility. It feels like a company with an identity crisis, caught between selling a tech solution and actually delivering a quality educational experience.

I regret signing up and would not recommend your service to others. At this point, I would have had a far better outcome using self-guided workbooks or teaching my child myself.

I hope you take this feedback seriously and make the necessary improvements—for the sake of other families who may not yet realize what they’re signing up for.

I never thought my son would get excited about math, but Cosmo just makes it click for him!

ClassUp lets my child learn at her speed! The learning partner helps change lessons to match how she's doing.

I'm impressed with my child's math tutor! Zain is dedicated and makes sure he gets each topic. My child feels good asking questions, and we're so thankful for her help!

Great Teaching, But Extremely Pushy Sales Tactics

The first free session was excellent—the teacher was engaging, interactive, and made the class enjoyable. My child loved it, and the learning experience itself was great.

However, the business practices were highly unprofessional. From the moment I filled out the registration form, the agent was relentless. There was no upfront information on tuition fees—I was first pushed to take an assessment and a free class before they would disclose pricing.

At the end of the session, I was pressured to commit to a package immediately. When I said I needed time to discuss with my spouse, the agent insisted I turn off my video and call him right away. The level of urgency and sales pressure made me very uncomfortable.

To make matters worse, just an hour after the class, I received a text criticizing my child’s writing with screenshots, stating that their essay was lacking in detail and would be a major obstacle for school and college applications. While constructive feedback is valuable, this felt like a scare tactic to push enrollment rather than a genuine evaluation.

Overall, while the teaching quality was good, the aggressive sales approach ruined the experience.

When I paid nearly $3,000 for a one-year package that included approximately 84 classes supposedly taught by tutors with experience certificates from top universities, I expected quality support for my 14-year-old daughter, who is taking honors algebra. However, the tutor, who appeared to be around the same age as my daughter, was unable to help her solve the problems. This was a troubling sign.

Many classes were missed, and when I asked for a refund, I was told I couldn't be reimbursed. Instead, they offered me additional classes as a solution. If the tutors are ineffective, why would I want more classes?

I strongly advise against spending your money on this program; it feels like a scam.

Scammers! I signed my son for 12 classes, got just 9.

Wonderful service team. They contacted me to schedule a free trial, sent me my daughter's progress reports, and helped us reschedule many times.

The lessons are well structured and the app makes it easy for my son to schedule classes. I can also keep track of what he has achieved. ClassUp has become a daily routine in our lives and he loves it.

Our daughter was struggling with math at school and her teacher broke down every concept that she failed to catch up with.

The lessons are engaging, interactive, and effective. My child looks forward to every class.

Two of my three children learn at ClassUp. Finally found an ideal tutoring platform. It's more like an online school than other tutoring services we can find. I think it works!

The free trial allowed us to experience the platform risk-free. Loved it!

The customer support team is amazing. We got replies very quickly once we asked them questions.

Our daughter benefits a lot from the personalized approach. She was very shy in school classes but ClassUp teachers encouraged her a lot.

They are very expensive. Over $50 for an ELA class per session this is too much. I have done online sessions with other providers for less than half a price of what Classup is charging. I hope they stop ripping people.

ClassUp lied to my credit card. We bought 24 classes for our two kids for the summer for $1,500, but we could not get a hold of the coordinator to change the original class schedule. When the summer ended and we had no classes used, we asked for a refund. The director texted me that he "really alarmed", but refused to refund us, saying the company "never as far as I know given a refund" even when ClassUp screwed up. When I disputed this charge with the credit card company, ClassUp told them that we were the ones who refused to communicate with them!

Mr. Ted is an amazing tutor! My son's writing improved dramatically after just four sessions. He's responsive, clear, professional, and has a great sense of humor.

The tutor helped our 8 yr old with his math. Very professional.

After reading all reviews in this Trust Pilot link, I understood that I am not the only one who complains about Class Up`s extremely poor customer service representative reviews.
There must be two level of reviews, one for ClassUP administrative support (which covers sales representation) and the other one instructors ( teachers) . Please see below my reviews :
1- I bought 12 English classes for my rising 8th grader during 2 months of summer period – at least 3 times our learning POC has changed. The person who assigned last was keep sending me text messages, emails and sending text messages via Class up app for any scheduling related items etc.… I kindly asked him that if there is a app and there is chat option why do you keep texting the same message via text messages. “ no answer”
2- The person who also called me couple of times 08:30 pm EST while we are having a dinner without giving any notice.. I told him if you want to discuss something about the class please lets find a mutual convenient time and kindly do not call me after working hours.
3- Once I sent him an email to clarify about the class satisfaction survey, he didn’t respond to me around 10 days. So I texted him and told him to respond to me via email… despite of my message he called me around 08:00 pm EST and left a voice message again ! I kindly told him to respond to my email- but he called me again and left a voice message , after couple of reminder finally he responded to me without answering some of my questions.
4- Long story short, ClassUP might be a good place for your kids’ educational support but sales support is extremely poor and needs to improve.
5- In regards to teacher , I give Classup 10 out of 10. We were lucky to have Ms. Elizabeth. She is an amazing teacher, and my child was very happy.
6- If you ask me to move forward with another class with ClassUP I say “ no” until they fix this poor sales support . I hope our paths cross again with amazing teacher Ms. Elizabeth. I hope the Class up management takes some notes in terms of their poor sales service, provides training to their team, improve this service; and I hope class Up team find a constructive solution on this issue.
