If he really does put his mind to it, and you just guide him along, then, I am very confident that he can succeed.

As for his laziness and easy influence, try to make that place more firm, such as giving him responsible things to do, and a concise knowledge of what the world is like. Usually, the kids who end up “bad” are the ones that had little knowledge of the outside and wanted to explore.

If he does not happen to not get the grades he want, true, he will be disappointed, but he will be more disappointed if his parent’s show disappointment at him. If such a thing happens, just encourage him, and tell him that you are proud.

As for studying, the best course is to develop a well drawn out study program. Cutting down but not eliminating his “free time/material” to encourage studying will help, as well as mentioning the fact that if he pulls through well this year, then he can make it in, and be set for a secure future.

Medical schools look at your college’s GPA, the MCAT, and also the person, (i guess). also, he could change his mind by the time he graduates from high school and from college.

for now, just support him in getting his grades up. He seems like a great kid and keep encouraging him.
