I signed my child up for their 36 lesson-package ($1950) at the start of 2026. We went ahead with COSMO because the trial went well and the tutor assigned happened to fit our child's learning style. We also felt the warmth and enthusiasm coming from their consultants. After having committed to class package, we were assigned a different consultant to follow-up on any "issues" or "help needed". Following the 1st trial, we had countless moments where technical issues surfaced and perhaps due to time difference, the team is unable to respond promptly. Some issues are, the tutor would be doing a practice work with his slide, but we cannot view it, or it is very laggy. This connection issue we face only happens with COSMO app/classes.

Currently, we are only able to attend the classes on the ipad, but often with glitches. My child can only do the homework on my iphone when it is running on my Data plan but not my WI-FI. On the APP, it is advised that using a laptop allows a better experience. However, we are unable to even access the login page online. I would like to know if other parents/students from Singapore experience connection issues with this APP like we do. If this is a common problem, then perhaps the Cosmo team should investigate and rectify it before marketing to our region. If this is an isolated issue, I would appreciate more active response and follow-ups to assist us. At the moment, our experience is good with the assigned tutor, but the frustration kicks in when we do not get the prescriptive solutions when facing technical or connection issues. In short, this makes the learning and product experience feel short-changed.

If the product is available internationally, it is fitting to provide a hotline or troubleshoot consultant that is from the same region/timezone for better customer experience.

Cosmo App: Excellent Teachers Redefine Language Mastery

As an adult ESL learner, I have been using the Cosmo App for about a year now and have completed nearly 40 classes. I am extremely satisfied with my progress and the high quality of instruction. The core strength of the program lies in its dedicated teaching staff.I want to give a special shout-out to my favorite teacher, Mr. Jonathan. He is incredibly patient and always takes the time to explain things clearly. Through his ELA-focused lessons, which often dive into novels and poems, I realized that true language mastery is not about counting words or chasing scores. It is the ability to hear a joke and laugh, to read a book and get lost, to speak one's feelings, and to pen one's thoughts.

Really great program

Really great program! The teachers are patient, dedicated and the app is very easy to use, with lots of fun, interactive tools. Scheduling is very flexible and we have a dedicated rep who takes great care of us. Overall great way for my daughter to solidify what she learned in class.

30-Year Veteran Teacher Not Hired

I’m a 30-year veteran teacher and tutor. After a bout with Celiac disease and Pancreatitis I decided to enter the education system again. I have high reviews & am Montessori trained & have many, many years experience as an ESL & Special Ed teacher too. The job description of Cosmo does not state that you have to be a Harvard or Stanford graduate, but apparently after looking into the matter, I discovered Cosmo only hires 1% of all applicants & that they are Harvard & Stanford educated. This is discrimination. Pit me up with one of your Harvard tutors any day & I am sure I will do just as good as a job as they. I may consult a lawyer.

None stop calls and harassment

I am very interested in this for my daughter but the education advisor Edward Liu keeps calling, texting and emailing me nonstop. After I told him I would get back to him he's calling my phone all day late hours, on Sundays and it's annoying. I blocked his numbers guess what he emailed me after I mentioned several times he keeps messaging and calling, now he's emailing me. Unless I get someone else I don't want to sign up. He has no boundaries, overwhelming me and forcing me to decide by sending 60 minutes discount links one after the next yet claiming his manager gave him the authorization to extend the discount.

Education agent just keeps calling

We saw an add on FB and thought of trying out a trial class and get to know about the payment structure for our kid. However upon review we found the fees were too high for us to afford and we did let them know. We again received a call after around 3 weeks and and the agent who herself was having an accent just kept pushing for their class and telling how other online classes are not as helpful. I believe they need to respect our decision and leave us alone once we have respectfully given our decision. I am writing this review because I am really frustrated with the call.

Unable to set up Interview

This is a highly unprofessional way to attempt to have qualified educators join your Team.Numerous messages, emails and phone calls were not followed up efficiently.Is there a company affiliation with national accreditation?

Invaluable writing support

Cosmo has been a game-changer for my son's writing skills; the feedback is spot-on, and he actually enjoys writing now.

As a career woman and a mom

As a career woman and a mom, I appreciate the detailed reports Cosmo sends every month - it shows my child's progress, so I know it's effective.
