<p>For me, 4 years of chemistry was much easier than 4 years of biology because chemistry dealt with much simpler systems that were easier to grasp. Also, the quantification aspect of chemistry doesn’t make chemistry harder, it makes it easier.</p>
<p>Biology deals with systems that are extremely complex. It’s no wonder that you need to know soooo much more. The amount of information is large…and growing daily. It truly is impossible to grasp just how complex living systems are…</p>
<p>But biology doesn’t happen isolated in nature. Physics and chemistry are at play too. So if you want to really learn it right, you have to learn it within the context of math, chemistry and physics too. Most people (especially premeds) don’t learn it this way because it isn’t necessary. But I would advise anyone interested in a biology career (ie molecular biologist, geneticist, etc) to learn all the sciences because it will make him/her a much better scientist.</p>
<p>Good luck.</p>
