Hi everyone! I am applying this cycle and currently working on my secondaries. I am referencing MSAR for my schools and noticed a few things Some specify that they PREFER committee letters, while others say "Accepted" for committee letters, letter packet, etc. I am still waiting on a LOR...

I go to a community college and there are no other colleges/universities in my area (for at least 90+ miles). My college does not offer biochemistry! I am really frustrated since I know I could take it online at another university, but that doesn't look great for admissions from what I've heard...

I've started my journey for fulfilling Pharmacy pre-requisites with Portage Learning. I've asked the pharmacy schools that I am interested in attending about portage learning and they accept to credits! So far, portage learning is the most cost effective option I found regarding online...

Hello, I am a pre-dental student. I am entering my 3rd year and I am taking Ochem II, Genetics, and Analytical Chemistry. How hard is my semester going to be, ball park? I passed Ochem I with a C and struggle to understand the material.

I am a sophomore chemistry major, and am about to take organic chemistry. I have just recently finished gen chem 1 and 2 in the spring and summer semesters, and earned A's in both. From what I hear, Orgo is a completely different animal. I have just under a month before the class starts, and...

Hi everyone. Just curious how to list certain things? I understand we get ten - fifteen slots and three can be most meaningful. Organic research - did it for a bit, had a thesis, defended it and presented at multiple conferences and received several research grants. Should these be listed as...

Hello everyone, I was wondering how to proceed. I will be taking my MCAT in June, and my school requires a minimum 500 MCAT for a committee letter interview. By taking in June, I will have the score by July, and the GPA requirement is a 3.5. Is it considered late? My plan was to submit...

Hello everyone, Basically, I did research with an Orgo professor. However, I did NOT take him for Orgo II. I did an independent study/research credit with him; and received an S (for satisfactory completion). So, I did research w him for a bit, presented my research, and even got a thesis. Is...

Hello. Just curious if there are schools that do this? I saw threads on here but most of them seem to be at least five years old. I was wondering if schools like BU still take your last 32 credit hours? Also, how does this match up to MSAR? MSAR reports GPAs of a lot higher than what I see...

Hello all. Wondering how it would be for a Canadian applying to DO/MD schools? Did all my schooling here in the US, have the GC pending (have not received it yet). i know there are some DO schools; and Im looking at applying DO anyway... Stats arent great but wondering which schools I may...

I am in post-bacc at CSUEB and I am almost finished but my advisor recommended I take some more chemistry classes before I graduate. She recommended Biochemistry II so I registered but after our first day of class I realized its very similar to a class I took in undergraduate that was on...

Hello, I am currently a senior in college. My goal is to go to optometry school, but I am worried 4 C's will hold me back. So far I have gotten a C+ in an ecology and evolution class, and C's in ochem 1&2 and in biochem. I took biochem this semester, when everything transitioned to being...

About me: 2020 psychology graduate, starting formal post-bacc in September. My questions: 1) Would you say that reviewing Khan Academy videos would be sufficient "prelearning"/prep for General Chem/Bio for someone who has not studied either subject since high school? (4 years ago) I was...

I just never really put...

I'm about to sign up for gen chem 2 for life scientists for Winter 2020, and I'm stuck between 2 choices. There's 2 sections, and one of the professors (Prof A) is the one I have Gen Chem I with currently. His exams are easy and straightforward, but he seems to skip over some things that other...

Howdy!! To sum up my situation, I want to briefly mention that for a long time I have had a lot of motivation towards being a doctor and pursuing medical school. During high school, I was a huge math nerd and was never huge into the physical sciences, but for a while since my senior year, I...

So I am in biochemistry right now and have my first exam in two days. A lot of the material is built off of prior orgo and gen chem knowledge, as this first exam is on amino acids, functional groups, pka curves, and hemoglobin/myoglobin saturation curves, however I just bombed my second quiz on...

Hey guys so im studying for the MCAT, but I just found out that we can't use a calculator and honestly I'm lost on how im supposed to answer, for example, physics-related questions with no calculator. Does anyone have any tips on how they got around that

I will be presenting and am currently in the process of making my poster. I was wondering if there was a specific template to follow? I feel like I've been trying to find one but can't. Really don't want to use my school' template xD Wondering if you guys had a link? Thank you so much!
