your platform is literally saving me in my studies, im in year 10 and this 6 minute video explained something my teacher couldn't in weeks

[@o5048]

Covered this in 6 minutes My teacher couldn’t explain this in a week

[@abidmajid1]

So true

[@aleenaibrahim2319]

True

[@r.i2007]

they don't get paid well enough to really want to teach thats why.

[@bethlongstaff9548]

agreed

[@emilliegibson7699]

It's quite fun to just surf through your lessons, cry at the complexity of half of the teacher explanations, and then come here and listen to you cover it simply in, like, 5 minutes or so. It's really helpful. :D

Not too long at all, really well explained. Thank you

[@isobelchester2458]

Hi! This video was definitely not too long, I found it was the perfect length to consolidate and take further notes during home learning.

[@KeepLearing]

It's not long, it's perfect - because the structure, content and animation was exceptionally planned ❤

You’re very welcome! Thanks for leaving us a comment really appreciate it

[@tonyzambonistarkoni7868]

Great explanation but you missed the main reason why placebos are used- because of the placebo effect, when the patient expects to feel better and their brain is tricked into thinking the symptoms have been treated even though they haven't, so they feel better anyway. Placebos are used so you can see the actual effect of the drug rather than just the placebo effect

[@freyadcoding8244]

This length of videos is amazing and fits well with the way I take notes. Also, I just want to say thank you for these amazing videos that have, quite frankly, saved my life. God Bless.

[@nooryousaf3113]

longer videos are actually really nice. Thank you :)

I believe that the length of the video was very appropriate for the topic that you were covering. Thank you for helping GCSE students getting a high grade. PS. will you have chemistry as a subject as well?

[@casparasaam6903]

@@Cognitoedu do you also have videos for the higher tier exams?

[@Cognitoedu]

Hi Caspar, check the description of the videos. We’ve updated many of them to say whether certain parts of the videos are higher tier or not. On the older videos there’s sometimes a higher tier label that appears. Be sure to check the syllabus to make sure you’re not missing anything though :)

[@liaxqu]

[@doomskull7549]

wait so are the volunteers tested against a placebo healthy or suffering from the illness?

[@dylanwarrick5827]

Bit late but in the clinical trials where there is double blind (neither doctor nor patient know whether it’s the real drug or placebo) the drug is usually be tested on people suffering from the illness/disease. This can be unfair though, obviously if the drug works, the people who are taking the placebo might have already died from the illness even though they would have survived if they were given the real drug.

[@doomskull7549]

@@dylanwarrick5827 I passed my gcse now lol but thanks anyway; that's pretty interesting

[@Rae-jq9bm]

Heyy.. I had a doubt What is the purpose of doing the placebo thing?

[@ninabird745]

Well sometimes if you think that you're going to get better, it increases the likelihood of you getting better, so they want to make sure that the effect the drug has is actually because of the drug, not just because you think there will be an effect. It's kinda to do with the psychology.
