fallback,

Our goal for the 100 Week Sprint is to increase the value of your MBA investment. As we talked with previous students, many of them shared how much their confidence in the program was dependent on their early preparation.

This week is about providing you resources, classes, and programs that can help you to get ready for school in the fall!

To-do's this week

Got 5 minutes? Take the Excel quiz to see how you fare.

Got 30 minutes? Excel skills could use a refresher? Check out our recommended resources.

Got an hour? Consider the areas where you're a bit rusty. Download an app or two and give yourself a quick review in your spare time.

Have many hours and want to be really prepared? Consider in-depth preparation courses, including Math for Management. Given the importance of modeling in many programs (and how much advanced skills can make your life earlier), consider Training the Street or other similar programs.

Be prepared to use Excel

"One area where I still feel I'm behind compared to my peers is Excel, since I did not use it very often in my career. I wish I had done some sort of Excel training to learn all the shortcuts that dazzle and amaze me when my friends make spreadsheets do magical things." - GSB Student

Even after years of consulting or banking, many MBA students are surprised by how much more Excel can do than they imagine. Mastering it can make you (a) more efficient in your own work and (b) a helpful resource for classmates.

An Excel whiz in my class changed my second year MBA experience. She saw me agonizing in the cafeteria one night, struggling to create manual sensitivity tables in Excel for a finance class. She introduced me to table functions that I used almost daily in my first year post-MBA.

Save time later, brush up on math now

Getting back up to speed now means that you are less likely to get bogged down in class in your first term. The question is, should you build your math momentum now, or tackle it later when recruiting is top of mind? Prior 100 Week Sprint subscribers agree that tackling it now will save you time and stress later on.

Consider these options to start refreshing your math memory today. Choose from online videos, books, or apps to get ready for school.

Looking for extra credit?

Check out Harvard's Certificate of Readiness program, also known as the HBX CORe. This course will be particularly helpful if you are a "non-traditional" candidate with a background other than business (e.g. sciences, media, etc.). Current MBA students have noted that the accounting portion of the program has been particularly helpful!

Looking to feel extra confident? Try Training the Street. This program is intended for professionals intending to have a career in finance, however, the rigor can prepare you for many of the assignments you are likely to face over your two years in school. While many classes do not require this level of knowledge, many students have noted the confidence that this level of training has provided.

Are you considering quantitative classes (anything from finance to marketing analytics)? Consider training in R, Tableau, SQL, and SAS which can be helpful for analytical work across multiple industries.
