thanks so much❤
Thank you so much sir.
Thanks sir❤
Very very thank you so much❤
my mock is tomorrow thank you loads!!!
Great video! However, there is some confusion about the units used. 1000 Kilobyte (KB) => 1 Megabyte (MB). These are the correct conversion of the units used in the video, powers of 10. 1024 Kibibyte (KiB) => 1 Mebibyte (MiB). These, on the other hand, are in powers of 2. In IGCSE settings, your questions will be asked in units of powers of 10 (KB, MB, GB..), not the other units.
CAN YOU PLEASE DO MORE PAST PAPER WALK THROUGH PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE
Thank You very much
Thanks it really helped me alot
For ascending, what will we write?
asc; or nothing because default is ascending so not really required
Great work❤❤
Hey man, your channel is really helpfull im just wondering whats the best way to convert between units like how do you divide 1024 without a calculator
i love you thank you for this

Thank you so much❤
bro your answer is wrong you have to get the answer from top to bottmom
no, the answer is correct. You simply need to approach the solution by reading it from the bottom upwards.
What I did File size=40000bit Total size of 10 pic=40000*10=400000 Bytes=400000%8=50000 Kb =50000%1000=50kb Is this fine?
Why not pos
Monday ko paper ha pseudocode bilkul nahi ata yarr koi recommendation??
Thanks brother
