This great man did what a school tries relentlessly to do in 2 years, in literally half a days' worth of time.

[Saif-ccjq]

Good luck to the first batch including myself that's doing space physics this year. Unarguably the batch with the most odds stacked up against them.

[AwesomeDooshi]

I actually have started loving physics because of your videos. Thank u 🙏

[nevaehjol]

sir u explained a concept that I struggled with for two years, why didn't I know you earlier

[devikas.]

you should solve past paper questions too, that would be fun to watch!

[cooller]

oh my days, god bless u. My teacher is so trash at explaining and u literally made me understand everything in one video, i love you. ❤❤❤❤❤❤ i will subscribe and rely on ur videos, and i will get a 9 on my igcse cuz of u. ur students r so lucky

[huskyfan]

All the best to this year's IGCSE candidates, including myself. Space physics is my only favourite chapter for the whole Physics syllabus. I am personally glad it is added to the syllabus (better than having barometers and manometers)

[neha_reddy]

I have my physics preboard in a week! You explained a chapter I had lots of doubts in so effectively. Thanks a bunch!

[inderbirsingh]

Sirrr, i have my mid term exams tomorrow and due to shifting schools, i am not done with the syllabus which is coming out in the exam, your videos helped me learn all of the concepts super fast.
You are the third teacher i have met in my life so far who teaches physics with so much enthusiasm. Thanks a lot sir, u aint got the name mohammed ali for nothin. W

[cappybaraeats]

im so angry at myself that i only found this channel now when Im literally having igcse phy exams in 4 days .

[maahishah]

Thank you soo much sir!!! You made this topic 10 times easier to understand. Once I understood the concept, I started having a lot of fun in learning topic instead of thinking it was deadly and extremely difficult. It's all thanks to you!!

[khizerahmad]

Very good explanation. Not long, but very well explained. This video helped me to prepare for my school examination for physics.

[Adam-dnbq]

I am amazed by your explaining Mr.Mohamed thank you so much

[cappybaraeats]

omg no wonder i got so confused with the current direction stuff because like they literally said electrons but then the direction is the opposite?!?! like it was literally contradicting themselves... luckily i found you teacher omg i finally get it

[abdullahalali]

you are a hero
this will save a lot of time
thank you!!!

[Allahthesupreme]

This man is my first sight love because the way of the expression and teaching skills are remarkable best physics teacher in the world

[AnnAnn-ojct]

Sir, you really are a life saviour !!! You just explained all at once in 2 hours which I've been struggling for two years... I'm so glad that I found you earlier before my final exams is getting close and you kinna make me love Physics now which I've been considering as my archenemy loll... Thankyou so much Sir! May God bless you Sir!

[MarvellousHarrison]

I literally wrote a mock today against next month exams and the last question you asked about why voltage is increased came out, and I just smiled thanking you so much in my heart.

That was just one among the numerous other questions your videos helped me answer.
