2019 MacBook Pro user, they made me download and run chrome to take the exam, last time (July-flex for me) they let me use Firefox. I am not sure if that's even a choice now, so have Chrome as an option just in case!
On 7sage they charge by the hour for general consulting. There are also packages that you can buy for set prices. I don't know how other entities charge.
@studentservice should be able to get you sorted. They have hourly rates of 200 or 250 I believe, plus single edit and single essay packages as well as full service consulting. They do consultative calls as well.
If you want to talk to someone about 7sage consulting and what is best for you, send an email to editors@7sage.com. Speak with David and he will be able to advise you. Good luck!
Random question for @"selene.steelman" - is there a “best” admissions consulting company? It seems like there are so many out there ... I’d love your thoughts on the best! Or anything we should avoid?
