Can i prepare for SAT in a month to score 900+?

Im from India and im planning to apply to Concordia uni, Irvine. Their application deadline for fall semester is on June 1st. They ask a minimum SAT score of 900 (Math & critical reading) for admission. To be honest i dont know much about the SAT.
My family cannot afford coaching classes at the moment and im thinking about self studying for it. Its already the middle of January now, if i get the SAT blue book and self study would i be able to get a decent score by appearing for the March SAT exam? and also, as far as i know, SAT has three parts - Math, critical reading & writing. but the academic requirements in the uni website states “MINIMUM TEST SCORE- SAT = 900 (Math & Critical Reading)” does that mean i wont be doing the “writing” part or just that it wont be considered?
also can you tell me if 900 in Math & critical reading is too far fetched to get under the circumstances ive mentioned?
what would you suggest i do to get a decent application?
sorry for being bland but im very confused at the moment and i need some advice! thanks in advance…

A 900 M + CR is a very low score. I am not familiar with the school you are interested in, but if that is the minimum they require to get in, you might not be happy there. Why not study for the test (both my kids self-studied) then see how you do? Once you have your scores, you can compare them to the middle range of accepted students in a variety of colleges,

I agree with Massmomm. Probably best to look into other colleges - a 900 is not much to ask for. If you are going to study to get a combined score of 900, a month should definitely suffice. Collegeboard provides plenty of free tests along with explanations and answers, so you should be set to go after taking 4-5 of those.

You must do all three sections (R, M, W) when taking the current SAT.

900 CR+M is indeed a low cut off. Take a practice test first, see how you do.
