A2 Biology: Ultrafiltration, Selective Reabsorption and the Reabsorption of Water

[@ummewaseem5983]

Also, just wanted to say the detail you go into with your videos is quite unique something that's very valuable to us students so please don't sacrifice that for shorter videos in the future. I really don't mind your videos being longer than the average revision video since you provide so much more clearer detail and depth :)

[@gracea4773]

Umme Waseem I agree

[@aynaz2422]

I agree too

As a self study A level student, i was REALLY struggling to wrap my head around this and this video has made it all make sense! Thank you so much!!

Why did I find your channel the day before my exam. Wish I knew of your channel from first day of sixth form 🤭😅

[@glaxyjoseph]

I was struggling so much with all these concepts. In the textbook and notes it was in three different sections, I'm just sat there going back and forth trying to figure out where the connection is. Was stressing because of exam next week. Omd my brain was drowning and you officially just saved me!! Your flow of explanation is amazing. It makes all sense now. Thank you so much!!

[@LSCBiology]

happy to have helped!

[@fatimakhan409]

The best explanation hands down! loved how you took your time to repeat the concepts, write them down. Absolutely brilliant. Good that you in such wonderful depths! just discovered you and liked and subscribed. Please tell me you have a channel for Physics and Chem too?

[@LSCBiology]

I'm happy you found our channel helpful. We do have a Physics channel run by the Physics teachers here (LSC Physics) and a Chemistry channel (LSC Chemistry), but the Chemistry channel is still in early stages of development.

[@monicasier7373]

HAAAA!! My favorite part of the video is the awkwardness @ 13:40-13:45. The look he gives the camera, as if someone he cared for watched him drop the marker cap. Dr. Bhavsar.. I thoroughly enjoyed this small lecture. You are as handsome as you are awkward. I can imagine you studying to master this information. :)

[@worldtvtv]

Thank you a million times over. Honestly i'm beyond grateful for your channel and most importantly this video. I'm so glad i wasn't put off by the 31 minutes 39secs. Being impatient i just increased the speed of your video to 1.5. Your teaching style is impeccable. God bless you. Such clarity. I'm speechless. You've just gained a subscriber x
