It's not too late, but as @twogirls ls said, you won't be applying next year. D1 only decided her senior year of college she wanted to try for med school. She's now a physician, but it took her 3 years after her college graduation to get her pre-reqs & ECs done before she applied.
You don't need to change your major. (D1 & D2 both went to med school. They had classmates with majors that include forestry, music performance, theology, Spanish and business, as well as the more typical science/engineering majors.)
However, med schools do have a defined set of required coursework you must take to be considered for admission:
2 semester biology w/lab
2 semesters general chem w/ labs
2 semesters organic chem w/ labs
1 semester biochem
2 semesters physics w/labs
2 semesters college-level math, one of which needs to be statistics or biostatistics
2 semesters college composition
1 semester psychology (required at some schools, tested on the MCAT)
1 semester sociology (required at some schools, tested on the MCAT)
Generally speaking, med school admission committees strongly prefer that pre-reqs be taken at a 4 year college, not at a CC. (Although osteopathic med schools are more lenient about this.)
You could delay your graduation and take your pre-reqs at your current college or you could graduate and do a post-bacc program for career-changers. Post baccs range a great deal in price and vary from very structured to a piecemeal do-it-yourself option. Formal post-bacc tend to be very expensive ($60K or more). There is no financial aid available except for loans to pay for a post-bacc program.
Besides having the right coursework, med schools are looking for people who know what they're getting into and have demonstrated the qualities they find necessary to be successful doctor. There are numerous expected ECs that successful med school applicants have-- community service with vulnerable and underserved populations; clinical volunteering; physician shadowing; demonstrated leadership; and for some schools (particularly at highly ranked, research oriented schools) significant bench or clinical research.
If you have never done any clinical volunteering or physician shadowing, I would suggest doing both is a necessary first step before you invest your time, effort & money into becoming a pre-med. You need to know if you want to spend the next 10 years of your life preparing to become a physician.
One more thing you need to consider before committing to this path-- every year 60% of medical school applicants do not get an acceptance to medical school.
Make sure you have a Plan B.
ETA: If you only want to be surgeon and nothing else. please don't go become a pre-med. The vast majority of med students end up in one of the primary care specialties (family medicine, general internal medicine, pediatrics, OB/GYN or psychiatry.) While general surgery isn't especially competitive, there are zero guarantees that you will qualify for or match into a surgical residency.
Only consider med school if you are willing to go into it with an open mind.
Also, what is your current GPA?
Med school admissions used GPA as a screener when considering applicants. Last year the average GPA for successful applicants was 3.7+ for allopathic med school applicants and 3.58 for osteopathic med school applicants.
You start by retaking any science/math classes you earned a C-D-F in. Although grade replacement is not permitted, newer, better grades will go a long way to convince a program you have the necessary foundational knowledge, study & time management skills and determination to be successful in upper level electives.
There is no magic shortcut to fix a low GPA. It's a long, tedious process.
There is very limited FA available for post-bacc. The only financial aid you'd qualify is a federal unsub loan up to $20,500/year. If the program you attend cost more than that, you'd need to qualify for a private loan or have a willing & qualified co-signer for a private loan.
Also, what about UC-Colorado Springs? CU SOM has a medical campus there as well as in Aurora.
Truthfully, just about any college in the US offers the coursework needed for med school. Getting the necessary ECs--shadowing, community service, clinical volunteering, research experience--that's all on the student. Most colleges--even smallish LACs-- have research opportunities. (And if not, there are a plethora of summer research programs). Clinical experiences does not need to be done at hospital, and especially not at Level 1 research hospital. (Hospices, nursing homes, long term care facilities, community health clinics, Planned Parenthood all may offer more meaningful clinical volunteer service opportunities than handing out magazines to people waiting in the ER at university hospital. Less competition for those volunteer slots too.) Community service with the less fortunate--that can be done anywhere.
