April 28, 2020 – Day 29

9:59 PM – I’M FINALLY DONE WITH ACID-BASE EQUILIBRIA AND SALT EQUILIBRIA! YAY HUHUHU!! ❤ My mind’s already exhausted with all the calculations I’m trying to understand all day. I don’t know if I can finish Electrochemistry today, but I hope I can. If I can, I’ll be able to make Chem1 & 2 summary tomorrow.

1:45 AM – I’m ending today’s review session with great satisfaction. Turns out, I enjoyed Electrochemistry better than Acid-Base and Salt Equilibria. I’m only left with 3 topics of Electrochemistry (Nernst Equation, Corrosion, Electrolysis) & I’M OFFICIALLY DONE WITH CHEMISTRY!!!! (Just thinking of it makes me feel great HAHAHA). Keep up the study pace, self! Still got a long way to go,,, I guess I’ll just have to wake up at 6 am tomorrow so I can finish Chemistry early & proceed to writing chemistry key points. If I can finish both earlier, I’ll proceed with Physics right away. Though I can take a break, I choose not to YET. I’ll take an unexpected break once I REALLY FEEL EXHAUSTED AND OUT OF TRACK. I don’t feel that way at the moment so no break for the meantime, self.
