1 hr to go to office 20 kms away, 1 hr 15 mins to come back. On an avg, how much time do I waste everyday?

Finished Distance, Speed & Time from a GMATClub post. The tabular representation method is brilliant. It saved me a lot of time, since I don't have to keep writing the different forms of the formula S=D/T for every component of the question. Am definitely using the table form from now on! :-)

Also went through the post on Work problems. Didn't require much effort since my concepts are pretty clear. The only issue I have here is the time I take to solve a question, if I only rely on my concept. I will need to practice a lot of Work problems, and probably revisit my TIME notes for shortcuts. Buit I will get back to this post my diagnostic test, as the diagnostic test is untimed. Plus, there is only a limit to how much I can do in every topic over the next 2 days. Yup, probably giving the test on Saturday. Should revise everything on Friday. Phew...

Update on P&C: went through most of the solved examples in RS Aggarwal, need to wrap up Combinations with the last few questions from the book. Once this is done, need to go back to the GMATClub Math book chapter on Probability and try solving those examples I was having trouble with.

As for Remainders, still need to speak to that friend regarding the questions from the link I did not understand.

The probability of my reading the new Artemis Fowl novel on the weekend is...

Went through Combinatorics and Probability chapters in GMATClub's Math Book. Combi was easy, but probability - there were some methods of solving examples that I couldn't grasp. I've done these topics in school, and I had a brilliant Math tutor who gave me pretty much all the tools required to solve questions of this type.

Am going to go through RS Aggarwal's Class XI book to revise my old way of solving these questions. Hopefully, I'll be able to solve the challenging examples from GMATClub's Math book after that.

Btw, am "working from home" today. Project is more or less done, have to put in around an hour's worth of my time on wrapping it up today. So thought it was best to stick around the house and wrap up Probability during the day...

I actually want to finish up and revise my theory by Friday evening or max Saturday, give the OG Diagnostic Test, and get to reading Atlantis Complex - the new Artemis Fowl novel! I did NOT buy it when I saw it in the book shop on Saturday, because I knew I'd want to read but I need to study now to make up for my loss of 3 weeks. Damn work!
