Barts hemoglobin mnemonic

So I just came across a question asking me why Barts hydrops fetalis is lethal. The answer is because Barts hemoglobin can't release oxygen to the tissues.

And I thought, "Barts can't fart oxygen." as a funny way to remember this xD

What is Barts hemoglobin anyway?

Tetramers of gamma globin chains formed when there is deletion of all four alpha globin genes.

How do you remember Barts hemoglobin has gamma chains?
I made a sentence with a lot of B's and G's. I'm not even sure if you can call it a mnemonic.
"BiG bart bargains for bar games."
I don't know if it works.

Repeating PG entrance exam

"I'm a PG aspirant... This is my third year of PG preparation. I lost all interest in medicine. I've lost all hope too. I'm just tired of trying. I don't know who to talk to. I don't know how you get so much passion to write your blogs. I don't how to study also."

I understand that giving an exam for the third time must be really frustrating and tiring.

So my advice to you is - Make sure you prepare so well this time that it's your last attempt and that you get whichever post graduation seat you desire. Study real hard, no excuses.

It's natural that you tend to lose interest in learning repetitive facts. Maybe you should try hunting for new ideas, new perspectives and gain a different understanding of old concepts?

Google about facts you've learnt earlier. This time, instead of memorizing, think of why.

Question everything - Why does this muscle cause that movement? Why does sickle cell anemia cause leukocytosis? Why does phenytoin produce vitamin B9 deficiency?

Trust me, questions and curiosity will awaken an unexplored passion in you - The one you lost in studying the same things over and over again.
