This is a classic restriction question that students often overlook. Watch the setup carefully — Gly cannot be placed at either end, which changes the total number of valid arrangements. Students often ask which DAT study materials are actually used in real courses. The DAT Destroyer and...

Most DAT students think hybridization is easy — until they miss it on test day. The mistake? They memorize sp, sp2, sp3… but don’t understand how to count electron domains correctly. Hybridization is based on electron domains, not just bonds. That means lone pairs count, and double bonds...

What’s more important, if you’re already within top10%ish of your class? If I’m rank 3 or so currently, would it be more beneficial to study more on cbse at the risk and expense of dropping to rank 8-10. If it meant getting a better CBSE score (70+). or should I try to maintain what I have...
