So I picked up this book (Lehninger) for being too expensive, because obviously the more pricey the book is, the better it's quality in learning... stuff... and content... it probably cures cancer, who knows? Anyhow, so Im reading through the book and I come across a passage I don't fully understand (Shocking!), well... It depends: Sometimes the passage isn't clear enough about an ambiguous subject matter, and the issue is usually cleared up in the next few sections, however then comes the occasion in which I don't have a clue what the thingymabob is trying to Ar-ti-cu-late. Afterwards Im struck with the exercises. How the heck am I supposed to check if my answers are correct? It's not like I have a Biochemistry professor who could help. So why bother doing any exercises, if nothing changes if I do them or not. If they're correct, that's cool. If not, how cruel, either way I won't know until someone comes along to give concise answers. My questions- 1) - Why bother doing exercises if answers aren't provided, and I have no means of correcting myself? 2) - Who's the genius who charges 400$ for a hardcover textbook, without adding another few pages to... oh I dont know...... GIVE ANSWERS?! 3) - Is a career in biochemistry worth pursuing? Im technically applying in.. "pre-med", but I'm reconsidering medicine after I found out about serious corruption. My father wants me to be a doctor like he was, but I'm just not sure anymore... It's not like the work load is too difficult, just that I'd be more happy as a scientist than a civil servant.
